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}
Options:
Answer:
B
Solution:
When a spherical insulating ball and a spherical metallic ball of same size and mass are dropped from the same height, then magnetic field will act on metallic ball. If the earth's magnetic field is taken into account, then an induced eddy current will form inside the spherical metallic ball, thus retarding its motion. Hence, it will take more time than insulating ball.
