A short electric dipole (dipole moment P) is placed on the axis of a uniformly charged ring at a distance x from the centre as shown in figure. Radius of the ring is a and charge on it is Q. Write the force on the dipole when x=(a)/(2) and when x=a . why the direction of force at two points is different? (ii) is the force ont he dipole zero if x=0 ? if not where will you place the dipole so that force on it is zero.

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 :
