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}
Select the correct option:
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.
✓ Correct! Well done.
✗ Incorrect. Try again or view the solution.
