Charge `q_2`, is at the center of a circular path with radius r. work done in carrying charged `q_1`, once a round this equipotential path, would be.

Equipotentiai surface is a surface on which the electric potential is the same at every point:- A point charge +q Is placed at the centre of a sphere of radius B. An other point charge +q is take from a point A to another diametrically opposite point B on the surface of the sphere. Calculate the work done for this.

An equipotential surface is a surface with constant value of potential at all points on the surface. What is the amount of work done in moving a 2µC charge between two points at 3 cm apart of an equipotential surface?

An electron revolving round the nucleus acts as a magnetic dipole. A charge 2mC Is moving through a circular path of radius 0.15m with frequency 100Hz.Find the magnetic moment associated with the charge. path.
