The negative charge -q2 is fixed, while ...

The negative charge `-q_2` is fixed, while positive charge `q_1` as well as the conducting sphere S is free to move figure. If the system is released from rest,

A

both S and `q_1` move towards left

B

`q_1` moves towards right while S moves toward left

C

`q_1` remains at rest, S moves toward left

D

both `q_1` and S remain at rest.

Text Solution

Verified by Experts

The correct Answer is:
C

Net force on `q_(1)` is zero, while that on the conducting sphere is toward the left due to attraction of `-q_(2)` (fig SA 1.4)
