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}
Option: 1
Insulating ball will reach the earth's surface earlier than the metal ball
Option: 2
Metal ball will reach the earth's surface earlier than the insulating ball
Option: 3
Both will reach the earth's surface simultaneously.
Option: 4
Time taken by them to reach the earth's surface will be independent of the properties of their materials
Answers (1)
When metal is passing through earth's magnetic field, an eddy current will produce and it will oppose the motion, so it will take more time.
