Options:
  • A G shows no deflection
  • B G shows deflection on one side
  • C deflection of G to the left and right has constant amplitude
  • D deflection of G to the left and right has decreasing amplitude

The correct answer is: deflection of G to the left and right has decreasing amplitude
As a given pole ( N or S ) of suspended magnet goes into the coil and comes out of it, current is induced in the coil in two opposite directions. Therefore, galvanometer deflection goes to left and right both. As the amplitude of oscillation of magnet goes on decreasing, so does the amplitude of  deflection.
