The ratio of two charges is 2:3 and their distance of separation is 5 cm. If the force of attraction between them is 96 dyn, determine the magnitude the magnitude of the charges .

Two equal point charges ar placed in air 10 cm aprat and the force of interaction between them is 50 mg - wt . Determine the magnitude of the charges.

The magnitude of the two charges is doubled and the distance of their Separation is= also doubled The electrostatic force between them will :

The force of attraction (A) between two objects, whose masses are fixed, varies inversely with the square of their distance of separation 9d). The force of attraction between them is 2 units when the distance is 5 cm. what is the distance between the two objects, if the attraction between them is 8 units?

The force of attraction between two charges each of magnitude 3C separated by a distance 2m in air is

The force of attractions between two charges 8muC and -4muC is 0.2 N. Find the distance of separation.

The force of attractions between two charges 8muC and -4muC is 0.2 N. Find the distance of separation.

What is the percentage change in distance if the force of attraction between two point charges increases to 4 times keeping magnitude of charges constant ?

How does the distance of separation between two bodies affect the magnitude of the non-contact force between them ?

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 ?
