Experts kindly help me Given a square frame of diagonal length 2r
made of insulating wires. There is a short
dipole, having dipole moment P, fixed in the
plane of the figure lying at the center of the
square, making an angle d as shown in
figure. Four identical particles having
charges of magnitude q each and alternately
positive and negative sign are placed at the
four corners of the square. Select the correct
alternative(s).
