Viscous force is somewhat like friction ...

Viscous force is somewhat like friction as it opposes the motion and is non-conservative but not exactly so because

A

it is velocity independent while friction depends on velocity

B

it is veloctiy dependent while friction is not

C

it is independent of area like surface tension while friction depends on area

D

it is temerature dependent while friction does not depend on temperature

Text Solution

Verified by Experts

The correct Answer is:
B, D
Viscouse force between two layers of fluid depends upon relative velocity of layer and temperature of liquid while solid friction is independent of relative velocity of two surface in contact and their temperature.
