Question

Four point + ve charges of same magnitude (Q) are placed at four corners of a rigid square frame as shown in figure. The plane of the frame is perpendicular to Z axis. If a -ve point charge is placed at a distance z away from the above frame (z ll L) then (A) - ve charge oscillates along the Z axis. (B) it moves away from the frame (C) it moves slowly towards the frame and stays in the plane of the frame (D) it passes through the frame only once.

Correct answer is (a) - ve charge oscillates along the Z axis.

Q. Four point + ve charges of same magnitude $(Q)$ are placed at four corners of a rigid square frame as shown in figure. The plane of the frame is perpendicular to $Z$ axis. If a -ve point charge is placed at a distance $z$ away from the above frame $(z ≪ L)$ then

- ve charge oscillates along the $Z$ axis.

it moves away from the frame

it moves slowly towards the frame and stays in the plane of the frame

it passes through the frame only once.

Correct answer is (a) - ve charge oscillates along the $Z$ axis.
