Question Name: Charged particle and the metal block, 4

What is the direction of the electric field E? mE?m at location A due only to the charges in and/or on the metal block? (Refer to the rosette.)

With the metal block still in place, what is the magnitude of E? pE?p the field due only to the charged particle?

What is the direction of the net electric field at the center of the metal block (inside the metal)?

Explanation / Answer

1)

The electric field is radially outwards from a positive charge. (Answer is C)

2)

The positive charge will induce an electric charge on the rectangle. On the right hand side of the block the charge induced will be positive and on the left hand side it will be negative.

Because of the positive charge induced on the right hand side, the electric field will also point towards C.

3)

Both electric fields point towards C, so answer is also C

4)

It will be Zero at the center of the rectangle. (see point 2)
