Two charged particles placed at a separation of 20 cm exert 20 N of coulomb force on each other. What will be the force if the separation is increased to 25 cm?

Two point charges 9 muC and -2muC are placed at a separation of 20 cm from each other. (i) Calculate the electric potential energy of this system of two charges. (ii) What amount of work is required to separate the particles to infinite separation?

Two charges A and B of -5 muC each are placed at a separation of 20 cm . Another charge C of +3 muC is placed at a separation of 20 cm from both the charges A and B . What should be the nature and magnitude of the charge to be placed at the midpoint between A and B so that net force on charge C is zero ?

Two like point charges separated by a certain distance exert a force of 0.04 N on each other. When the distance of separation between them is, halved, the force exerted by each on the other will be

Two charges of +40 esu and -35 esu separated by a distance of 10 cm, exert 4 dyn force on each other. Determine the dielectric constant of the medium.

Two point charges are separated by some distance, repel each other with a force F. What will be the force if distance between them is halved?

Two particles of masses 1.0 kg and 2.0 kg are placed at a separation of 50 cm. Assuming that the only forces acting on the particles are their mutual gravitation find the initial acceleration of the two particles.
