Two parallel conductor carrying `5A` each , repel with a force of `0.25Nm^(-1)`. The distance between them is

The charge of one of two small charged conductors is twice that of the other. The two conductors repel each other with a force of 50 dyn. If the distance between them is decreased by 3 cm, the force becomes 128 dyn. What are the magnitudes of the charges ? What was the initial distance ?

The graph of force per unit legth between two long parallel current carrying conductors and the reciprocal of the distance between them is

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 point charges separated by a distance d repel each other with a force of 9N. If the separation between them becomes 3d, the force of repulsion will be

Two point charges separated by a distance d repel each other with a force of 9N. If the separation between them becomes 3d, the force of repulsion will be

Two point charges seperated by a distance d repel each other with a force of 9N. If the seperation between them becomes 3d, the force of repulsion will be

Two long and straight parallel wires are carrying current 1 A each. If the distance between the two wires be 1 m, what will be force acting per unit length on them?
