Three poistive charges of equal value q ...

Three poistive charges of equal value q are placed at the vertices of an equilateral triangle. The resulting lines of force should be sketched as in

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
C
Electric lines of force never form a closed loop. Therefore, options (B) and (D) are wrong. Electric lines of force emanate from positive charge and terminate on negative charge, therefore, option (A) is also wrong.
