THANK YOU IN ADVANCE

1. Suppose you put positive charge on a solid, insulated metal box (actually, remove electrons from the box). Since it is a conductor, the charges will rearrange.

a) On the outside surface, the greatest accumulation of charges will be

1)nowhere, since no charges reside on the outer surface, 2)at the center of each side, 3) at the corners , 4)nowhere, sinc the charges will be uniformly distributed, 5)at the center of each edge

b) In the inside of the box, the greatest accumulation of charges will be

1)at the center of each side, 2)nowhere, since no charges reside on the outer surface, 3)nowhere, since the charges will be uniformly distributed , 4)at the center of each edge, 5)at the corners

2. Suppose identical, neutral metal spheres A and B are insulated from their surroundings and touching each other. A positive charge is brought near but not touchingsphere A, and now the two spheres are slowly separated. Finally, the positive charge is removed. What charge will be left on sphere A and sphere B, respectively?

a)A is negative, B is negative, b)A is positive, B is positive ,c)A is neutral, B is positive, d)A in positive, B is neutral, e)A in negative, B is neutral, f)A is neutral, B is negative, g)A is negative, B is positive, h)A in neutral, B is neutral, i)A is positive, B is negative

3. Remember: the outer cylinder of the Faraday pail is grounded.
In procedure 1: suppose a negative charge is placed inside (but not touching) the inner cylinder of the Faraday pail.

a) The charge on the two surfaces of the outer cylinders are

1)neutral on both surfaces,2)positive on both surfaces ,3) positive on the outside, neutral on the inside, 4)neutral on the outside, positive on the inside, 5)negative on the outside, neutral on the inside, 6)positive on the outside, negative on the inside, 7)negative on the outside, positive on the inside, 8)negative on both surfaces, 9)neutral on the outside, negative on the inside

b) The charge on the two surfaces of the inner cylinder are

1)positive on both surfaces, 2)neutral on both surfaces ,3)negative on the outside, neutral on the inside, 4)negative on the outside, positive on the inside, 5)neutral on the outside, positive on the inside, 6)positive on the outside, negative on the inside, 7)positive on the outside, neutral on the inside, 8)negative on both surfaces, 9)neutral on the outside, negative on the inside

c) The net charge on the entire Faraday pail is

1)negative,2)neutral,3) positive ,4)cannot be determined from the information given

Solution

Q1. If you put charge on a non-conducting material, the charge will be distributed uniformly through the volume. And

If you put charge on a conducting material, the charge will be uniformly distributed only in the outer surface of the material and no charge reside at the inside of the material.

As the material is a conducting material hence

a) Ans: nowhere, since the charges will be uniformly distributed, throughout the surface.

b) Zero, As the whole charge reside on the outer surface of the box
