Insulating ball will reach the earth's surface earlier than the metal ball.

Vedclass · Answer

(B) When a metallic ball falls through the Earth's magnetic field,the change in magnetic flux linked with it induces eddy currents within the metal. According to Lenz's Law,these eddy currents create a magnetic force that opposes the motion of the ball. As a result,the metallic ball experiences a retarding force,causing it to take more time to reach the ground compared to the insulating ball,which does not experience such electromagnetic damping. Therefore,the insulating ball reaches the Earth's surface earlier than the metal ball.
