In which of the following case, attraction is maximum between two charged spheres separated by 2 mm distance ?

A

+2q and -2q

B

`+2q` and +2q

C

`-2q` and -2q

D

`-1q` and +4q

Text Solution

Verified by Experts

The correct Answer is:
A
There is repulsion between like charges hence (B) and (C) are not correct and for maximum attraction spheres should have equal charges of opposite signs.
