Passage / Comprehension
Figure shows the point electric charges of equal size and equally distant from the origin. Assume that the potential of the electric field generated by a point charge at infinity is zero.
In which case the total electrostatic potential energy of interaction of system is maximum :-
Options:
Answer:
A
Solution:
In case A all four charges are positive, so every one of the six pairs contributes - the largest possible positive total.
Any arrangement containing a negative charge turns some of these pair terms negative and lowers the sum.
Hence the total electrostatic potential energy is maximum in case A.
