JEE Mains · Physics · STD 12 -6. Electromagnetic induction
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 Time taken by them to reach the earth's surface will be independent of the properties of their materials
- B Insulating ball will reach the earth's surface earlier than the metal ball
- C Both will reach the earth's surface simultaneously
- D Metal ball will reach the earth's surface earlier than the insulating ball.
Answer & Solution
Correct Answer
(B) Insulating ball will reach the earth's surface earlier than the metal ball
Step-by-step Solution
Detailed explanation
When metal is passing through magnetic field, eddy current will produce and it will oppose the motion, so it will take more time.
