Two point charges separated by 16cm have a total electric potential energy of -26 J.If the total charge of the two is 95 μC, what is the charge on the positive one in μC?What is the charge on the negative one in μC?

Answers

Answer 1

Therefore, the charge on the positive point charge is 49.48 μC and the charge on the negative point charge is 45.52 μC.

The first step to solving this problem is to use the formula for electric potential energy:
U = k(q1q2)/r
where U is the potential energy, k is Coulomb's constant (9 x 10^9 Nm^2/C^2), q1 and q2 are the charges of the two point charges, and r is the distance between them.
Substituting the given values, we get:
-26 J = (9 x 10^9 Nm^2/C^2)(q1)(q2)/(0.16 m)
Simplifying this equation, we get:
-26 J * 0.16 m = (9 x 10^9 Nm^2/C^2)(q1)(q2)
-4.16 Jm = (q1)(q2)
We also know that the total charge of the two point charges is 95 μC. Let's assume that q1 is the positive charge and q2 is the negative charge. Then we can write:
q1 + q2 = 95 μC
We can now solve these two equations simultaneously to find q1 and q2:
q1q2 = -4.16 Jm
q1 + q2 = 95 μC
Rearranging the second equation, we get:
q2 = 95 μC - q
Substituting this into the first equation, we get:
q1(95 μC - q1) = -4.16 Jm
Expanding the left-hand side and rearranging, we get a quadratic equation:
q1^2 - 95 μC q1 - 4.16 x 10^-8 C^2 = 0
Solving for q1 using the quadratic formula, we get:
q1 = (95 μC ± √(95 μC)^2 + 4 x 4.16 x 10^-8 C^2)/2
q1 = (95 μC ± 3.96 μC)/2
Taking the positive solution, we get:
q1 = (95 μC + 3.96 μC)/2
q1 = 49.48 μC
Substituting this value into the equation q1 + q2 = 95 μC, we get:
q2 = 95 μC - 49.48 μC
q2 = 45.52 μC
Therefore, the charge on the positive point charge is 49.48 μC and the charge on the negative point charge is 45.52 μC.

12) Two-point charges each have a value of 3.0 C and 5.0 C and are separated by a distance of 6.0 m. What is the electric field at a point midway between the two charges?

Answers

Answer:

The electric field at a point midway between the two charges is 2 x 10⁹ N/C.

Explanation:

Given;

first point charge, Q₁ = 3.0 C

second point charge, Q₂ = 5.0 C

distance between the two point charges, R = 6.0 m

The mid-point between the two charges, r = R/2 = 3.0 m

3.0 C <-------------------->3.0m<----------------------->5.0 C

The forces are acting in opposite direction, the electric field strength of each charge is calculated as;

[tex]E_1 = \frac{kQ_1}{r^2} (-\bar x)\\\\E_1 = \frac{9\times 10^9 \times 3}{3^2}(-\bar x)[/tex]

[tex]E_2 = \frac{kQ_1}{r^2} (+\bar x)\\\\E_2 = \frac{9\times 10^9 \times 5}{3^2} (+\bar x)\\\\[/tex]

The net electric field is calculated as;

[tex]E_{net} = \frac{9\times 10^9 \times 5}{3^2} \ - \ \frac{9\times 10^9 \times 3}{3^2}\\\\E_{net} = \frac{9\times 10^9 }{3^2} (5-3)\\\\E_{net} = 2 \times 10^9 \ N/C[/tex]

Therefore, the electric field at a point midway between the two charges is 2 x 10⁹ N/C.

How do you know that Earth is affected by the gravitational pull of the sun ? Explain how you would be affected if you were able to safely move farther and farther away from Earth . Support your ideas

Answers

Answer:

The Sun's gravity pulls on the planets, just as Earth's gravity pulls down anything that is not held up by some other force and keeps you and me on the ground.

Explanation: Newton realized that the reason the planets orbit the Sun is related to why objects fall to Earth when we drop them. I am so sorry if I get this wrong, I'm in 5th grade! ♥

The Sun provides rotational motion to Earth by gravitational pull and if we get farther and farther, we will experience decreased gravitational force.

The Earth is continuously orbiting around the Sun, that is why we are experiencing the day and night everyday. And this orbiting is caused by the gravitational full by Sun on Earth, which is given as,

[tex]F = \dfrac{G \times M \times M'}{R^{2}}[/tex]

Here, G is the universal gravitational constant, M is the mass of Earth and M' is the mass of Sun. And R is the distance between the Earth and Sun.

If we suppose to move farther and farther away from the Earth then the strength of gravitational pull by Earth will decrease with the increasing distance. Because the gravitational pull is inversely proportional to square of distance.

Thus, we can conclude that the Sun provides rotational motion to Earth by gravitational pull and if we get farther and farther, we will experience decreased gravitational force.

What is force?

A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.

To find the acceleration,

   F = mg

   F = 80.(10)

   F = 800 N

   air resistance = 200 N

   Net force = F - air resistance

                = 800 - 200

                =  600 N

   600 = mass . acceleration

   600 = 80 . acceleration

   acceleration = 7.5 m/sec²

She will use one 2 and one 1 as subscripts. She will use one 3 as a subscript. She will use two 2s and one 1 as subscripts.

Answers

Answer:

She will use one 2 as a subscript.

Explanation:

Nitrogen is a chemical element with the symbol "N" and has an atomic number of 7. Thus, it is found in group (5) of the periodic table and as such it has 5 electrons in its outermost shell. Therefore, nitrogen has two (5) valence electrons.

On the other hand, oxygen has an atomic number of 8 and with the symbol "O."

When nitrogen and oxygen react chemically, they produce a compound known as nitrogen dioxide [tex] NO_{2} [/tex]

In this scenario, Jenny is studying a compound that has two oxygen atoms and one nitrogen atom. Therefore, the statement which describes the subscripts she will use to write the chemical formula is, she will use one 2 as a subscript.
