Two particles , each of mass `m` and carrying charge `Q` , are separated by some distance. If they are in equilibrium under mutual gravitational and electrostatic force then `Q//m (in C//kg)` is of the order of

Two charged particles each having a charge +q and mass m are kept at a distance d. if they are in equilibrium under the gravitational force and the electric force between them, then the ratio q/m or specific charge of each particle is

As shown in the adjoining figure two charge particles each having charge q and mass m and d distance apart from each other. If two particle in equilibrium under the gravitational and electric force, then determine the ratio q//m .

Three charged particle sare in equilibrium under their electrostatic forces only. Then

Three charged particle sare in equilibrium under their electrostatic forces only. Then

Two particles of equal mass m and charge q are placed at a distance of 16 cm. they do not experience any force. The value of q/m is

Two particles of masses 2 kg and 3 kg are at rest separated by 10 m. If they move towards each other under mutual force of attraction, the position of the point where they meet is
