Question

1. - 18 points SerCP11 15..P.039. My Notes Ask Your Teache Refer to the figure below. The charge lowered into the center of the hollow conductor has a magnitude of 2.9 p. Find the magnitude and sign of the charge on the inside and outside of the hollow conductor when the charge is as shown in the following images. (a) Figure(a) 120

Answer 1

(a)

The charge is not in contact with hollow conductor , hence

Q_inside = 0

Q_outside = 0

b)

due to negative charge on the hanging charge, an equal amount of positive charge is induced on he inner surface of the conductor. So

Q_inside = 2.9 $\mu$C

and equal amount of negative charge goes away to the surface to keep the hollow conductor neutral.

Q_outside = - 2.9 $\mu$C

c)

Due to transfer of charge, all the charge goes to the surface of hollow conductor, hence

Q_inside = 0 $\mu$C

Q_outside = - 2.9 $\mu$C

d)

The charge remains undisturbed on the surface of conductor, hence

Q_inside = 0 $\mu$C

Q_outside = - 2.9 $\mu$C
