The force of repulsion between two point charges is F, when they are d distance apart. If the point charges are replaced by conducted sphereas each of radius r and the charges remain same. The separation between the centre of sphere isd, then force of repulsion between them is

The force of repulsion between two point charges is F, when these are at a distance of 1 m . Now the point charges are replaced by spheres of radii 25 cm having the charge same as that of point charges. The distance between their centres is 1 m , then compare the force of repulsion in two cases.

The force of repulsion between two point charges is F, when these are at a distance of 1 m apart Now the point charges are replaced by spheres of radii 25 cm having the same charge as that of point charge and same distance apart. Then the new force of repulsion will

The force of repulsion between two point charges is F, when these are at distance 0.5m apart. Now the point charges are replaced by spheres of radii 5 cm each having the same charge as that of the respective point charge. The distance between their centres is again kept 0.5 m. Then the force of repulsion will

The force of repulsion between two point charges is F, when these are at distance 0.5m apart. Now the point charges are replaced by spheres of radii 5 cm each having the same charge as that of the respective point charge. The distance between their centres is again kept 0.5 m. Then the force of repulsion will

There is force of repulsion between two like charges, because electric lines of force
