Question

charges +q,+q,-q are placed at the three corners of an equilateral triangle of side l the potential energy of system is
(1)V=0,E=0
(2)V=0,E not equal to zero
(3)V not equal to zero,E=0
(4)V not equal to zero,E not equal to zero
​

Answer 1

Answer:

your correct answer is 3

Answer 2

Answer:

OPTION 3

E = 0 since the body is symmetrical and vectors will get cancelled.

V will not be 0 since it is scalar quantity and it won't be cancelled.It's magnitude will add up.
