As shown in figure, four electric charges are placed on vertices of a square and there is a free electron on it. Where this free electron will move ?

A

it will move toward A.

B

it will move toward B

C

it will move toward C.

D

it will move toward D.

Text Solution

Verified by Experts

The correct Answer is:
D
Resultant force by charges on A and C is zero. Due to B and D, electric force on free electron are toward D. Hence, resultant force will also be toward D. Thus, electron will move toward D.
