A solid sphere falls with a terminal velocity v in air .If it is allowed to fall in vacuum,

A

terminal velocity of sphere = v

B

terminal velocity of sphere lt v

C

terminal velocity of sphere gt v

D

sphere never attains terminal velocity

Text Solution

Verified by Experts

The correct Answer is:
D
When a solid sphere falls in vacuum, no viscous force is acting on the sphere and the sphere falls under gravity. Due to which sphere never attains terminals velocity.
