A charge +q is carried from point `A( r, 135^(@))` to point `B(r, 45^(@))` following a path, which is a quadrant of circle of radius r ( Fig. 3.97). If the dipole moment is P, find the work done by the external agent (assume short dipole).
.

A dipole of dipole moment P is kept at the centre of a ring of radius R and charge Q the dipole moment has direction along the ring due to the dipole is :

A charge q is removed from A to B in the region of a fixed ideal dipole P find the work done on the charge (Assume gravity free space )

A point charge -q is carried from a point A to anther point B on the axis of a charged ring of radius r carrying a charge +q. If the point A is at a distance 4/3 r from the centre of the ring and the point B is 3/4 r from the centre but on the opposite side, what is the net work that need to be done for this

A charge q is moved from A to B in the region of a fixed ideal dipole p. Find the work done on the charge (Assume gravity free space ).

If a point charge be rotated in a circle of radius r around a charge q. what will be the work done?

A charge q is moved from a point A above a dipole moment p to a point B below the dipole on equatorial plane without acceleration. Find the work done in the process.

A charge q is moved from a point A above a dipole moment p to a point B below the dipole on equatorial plane without acceleration. Find the work done in the process.

The work done in carrying a charge q once round a circle of radius r with a charge Q at the centre is
