Question

write formula for electric potential due to a dipole along it's axis and along it's equator​

Answer 1

Answer:

Distance AB = 2a, O is the mid point of the dipole and OP is perpendicular to AB. A charge Q is placed at P where OP = y and y >> 2a. The charge Q experiences and electrostatic force F. If Q is now moved along the equatorial line to P' such that OP′=(3y) the force on Q will be close to L : (3y>>2a)
