The force of attraction between two point charges at a distance r apart is F. What should be the distance apart in the same medium so that the force becomes F/3?what if force becomes 3F

If the distance between them is increased by √3 times the initial length then force will be F/3.

if the distance is decreased by 1/√3 times the initial length then force will be 3F.

Thanks and Regards

Force of attraction between two charges is inversely proportional to square of distance. So

F1/F2 = r2²/r1²

3 = r2²/r²

So r2 = r*(3)^1/2

Similarly if force become 3F then

r2 = r*(1/3)^1/2

Hope it clears.
