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):

• 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

Hint:

In the absence of air resistance, all objects fall at the same rate regardless of their mass or material.
