Two charges Q and q are placed at a distance ‘d’ from each other. If the magnitude of each charge is doubled and the distance between them halved, the force becomes?

Two identical point charges of charge Q are kept at a distance r from each other. A third point charge is placed on the line joining the above two charges, such that all the three charges are in equilibrium. Calculate the magnitude and location of the thrid charge.

Two electrically charged particles , having charges of different magnitudes , when placed at a distance 'd' from each other , experience a force of attraction 'F' . These two particles are put in contact and again placed at the same distance from each other. What is the nature of new force between them ?

Two points charges q_1 and q_2 are placed at a distance of 50 m from each each other in air, and interact with a certain force. The same charges are now put in oil whose relative permittivity is 5. If the interacting force between them is still the same, their separation now is
