Question

a body of 10 kg is kept on a rough horizontal surface which can offer maximum frictional force or 40 N what will be the frictional force when applied force is 20 N​

Answer 1

Answer:

Answer is 20N, You have to subtract 40N-20N.

Answer 2

Given :

The mass of the body = 10 kg  

The maximum frictional force offered = 40 N

To find :

The value of the frictional force when the applied force is 20 N .

Solution :

Frictional force opposes the force applied on the body but it has some limitations .

It can opposes force equal to its maximum limit by applying equal and opposite frictional force .

When the applied force is 20 N , the frictional force is 20 N .
