A dipole of dipole moment p is kept at the centre of a ring (in yz plane) of radius R and charge Q The dipole moment has direction along the axis of the ring. The resultant force on the dipole due to the ring is:

Question

Forum 1 · Answer

Solution:
Electric field due to ring at point P on its axis at a distance x from centre 0 of ring is (as shown in figure below)
E=k. [Qx/(x^2+R^2)^3/2]
dx/dE atx=0=kQ/R^3
∴Force on dipole=dx/dE=kQp/R^3
