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

it is velocity dependent while friction is not

it is velocity independent while friction is

it is temperature dependent while friction is not

it is independent of area is like surface tension while friction is dependent

Text Solution

Verified by Experts

The correct Answer is:

A, C

Viscous force is somewhat like a frictional fore but not exactly the same because it differs it due to the two main following statements.:
i Viscous force is velocity dependent while frictional force is not.
ii Viscous force is temperature depedent while frictional fore is not
So, options a and c are correct.

A body of mass 1kg is taken from infinity to a point P. When the body reaches that point, it has a speed of 2ms^-1 . The work done by the conservative force is -5J . Which of the following is true (assuming non-conservative and pseudo-forces to be absent).

When a liquid flows in a tube, there is relative motion between adjacent layers of the liquid. This force is called the viscous force which tends to oppose the relative motion between the layers of the liquid. Newton was the first person to study the factors that govern the viscous force in a liquid. According to Newton’s law of viscous flow, the magnitude of the viscous force on a certain layer of a liquid is given by F = - eta A (dv)/(dx) where A is the area of the layer (dv)/(dx) is the velocity gradient at the layer and eta is the coefficient of viscosity of the liquid. The dimensional formula for the coefficient of viscosity is :
