JEE Main 2023 — Gravitation Question with Solution

JEE Main 2023 (31 Jan Shift 1)

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}

Choose an option

Show full solutionCorrect option: B
Correct answer
BInsulating ball will reach the earth's surface earlier than the metal ball

Step-by-step explanation

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.
