Question

Spherical insulating ball and a spherical metallic ball of same size and mass are dropped from the same height. Choose the correct statement out of the following \{Assume negligible air friction\}

• A. Both will reach the earth's surface simultaneously.
• B. Insulating ball will reach the earth's surface earlier than the metal ball
• C. Metal ball will reach the earth's surface earlier than the insulating ball
• D. Time taken by them to reach the earth's surface will be independent of the properties of their materials

Answer 1

Answer: (B)

When metal is passing through magnetic field, eddy current will produce and it will oppose the motion, so it will take more time
