Two unlike magnetic poles of strength 10A-m each are held in air at a distance of 0*5m from each other. What is the magnetic force of attraction between them?

Two protons are a distance of 1 xx 10^(-10) cm from each other. The force acting on them are

Two ball with charges 5muC and 10muC are at a distance of 1 m from each other. In order to reduce the distance between them to 0.5 m , the amount of work to be performed is

A total charge Q is broken in two parts Q_(1) and Q_(2) and they are placed at a distance R from each other. The maximum force of repulsion between them will occur, when

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

Two equal charges are placed at a separtion of 1.0 m. What should be the magnitude of the charges so that the force between them equals of a 50 kg person?
