When a solid ball of volume V is falling...

When a solid ball of volume V is falling through a viscous liquid, a viscous force F acts of it. If another ball of volume 2 V of the same meterial is falling through the same liquid then the viscous force experienced by it will be (when both fall with terminal velocities).

A

`F`

B

`(F)/(2)`

C

`2F`

D

`(F)/(4)`

Text Solution

Verified by Experts

The correct Answer is:
C

`F=6pietarv(becausevpropr^(2),Fpropr^(3),FpropV)`
`implies(F_(1))/(F_(2))=(V_(1))/(V_(2))`
