A given charge is situated at a certain distance from an electric dipole in the end-on position experiences a force `F` If the distance of the charge is doubled, the force acting on the charge will be

A point charge placed at any point on the axis of an electric dipole at some large distance experiences a force F. What will be the force acting on the point charge when its distance from the dipole is doubled.

Two charges of equal magnitudes and at a distance r exert a force F on each other. If the charges are halved and distance between them is doubled, then the new force acting on each charge is

At a certain distance from a point charge, the field intensity is 500 V//m and the potentil is -3000 V . The distance to the charge and the magnitude of the charge respectively are

Figure shows a uniformly charged sphere of radius R and total charge Q. A point charge q is situated outside the sphere at a distance r from centre of sphere. Find out the following : (i) Force acting on the point charge q due to the sphere. (ii) Force acting on the sphere due to the point charge.

When an electric dipole is kept near a positive charge, it will experience

At a certain distance from a point charge, the electric field is 500 V/m and the potential is 3000 V. What is the distance ?
