Two similarly charged bodies are kept 5 cm apart in air. If the secnd body is shifted away from the first by another 5 cm, their force of repulsion will be

Two particles are placed in air seperated by a distance of 10 cm. 20 esu charge is distributed between them in such a way that the force of repulsion between them is maximum. What is the value of this maximum repulsive force in dyne?

Two positive charges of same magnitude are kept 20 cm apart. A point between the charges will have zero intensity is at

The force between two point electric charges kept at a distance d apart in air is F. If these charges are kept at the sme distance in water, the force between the charges is F'. The ratio F'//F is equal to ……….. .

The force between two point electric charges kept at a distance d apart in air is F. If these charges are kept at the sme distance in water, the force between the charges is F'. The ratio F'//F is equal to ……….. .

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
