Question

A solid sphere falls with a terminal velocity of $10cm/sec$ in air. If its is allowed to fall in vacuum, the terminal velocity will be

• A. equal to $10cm/s$
• B. less than $10m/s$
• C. more that $10cm/s$
• D. never be attained

Answer 1

The correct option is D never be attained

As there is no opposing medium in vacuum. So velocity will never become constant.
