A charge of `1 mu`C is divided into parts such that their charges are in the ratio of 2: 3. These two charges are kept at a distance 1 m apart in vacuum. Then, the electric force between them (in N) is

A charge of 1 mu C is divided into two parts such that their charges are in the ratio of 2:3 .These two charges are kept at a distance 1 m apart in vaccum. Then,the electric force between them (in N) is

Two charged particles are a distance 1 mm apart. Find the minimum Coulomb force between them.

Distributed charge of 1 C into two parts such that these part a experience the maximum force when they are kept at a distance of 1 km.

What is the force of repulsion between two charges of 1C each, kept 1m apart in vacumm ?
