A solid sphere falls with a terminal velocity `V` in `CO_(2)` gas. If its is allowed to fall in vacuum

Terminal velocity of sphere `=V`

Terminal velocity of sphere `ltV`

Terminal velocity of sphere `gtV`

Sphere never attains terminal velocity

Text Solution

Verified by Experts

In vacuum there is no gravity so solid sphere will not attain terminal velocity
