Question

An iron ball and a wooden ball of the same radius are released from a height 'h' in vacuum.
The time taken by both of them to reach the ground is

• A. Unequal
• B. Exactly equal
• C. Roughly equal
• D. Zero

Answer 1

The correct option is B

Exactly equal

Time of decent $t=\sqrt{\frac{2h}{g}}$. In vacuum no other force works except gravity so time period will be exactly equal.
