Question
A force of repulsion between two point charges is F, when these are at a distance 0.1 m apart. Now the point charges are replaced by spheres of radii 5 cm each having the same charge as that of the respective point charges. The distance between their centres is again kept 0.1 m, then the force of repulsion will - increase
- decrease
- remain F
become
become
Solution
C.
remain F
