the force between two point charge is F when these are at distance of 1mt apart . now the point charges are replaced by spheres of radii 25cm having the charge same as that point charges . the distance between their centres is 1 mt . then repulsion force between these spheres is F' then comparison between F and F'

Answer:
The force of repulsion between two point charges is F, when these are at a distance of
. Now the point charges are replaced by spheres of radii
having the charge same as that of point charges. The distance between their centres is
, then compare the force of repulsion in two cases.
