Question

A small block of mass m is kept on a rough inclined surface of inclination . The block does not slide on the surface. The work done by friction on block in time t will be

Answer 1

Answer:

Zero

Explanation:

Work done is given by F.S

where F is force and S is displacement

See ,Force is there , I mean friction is a self adjusting force and if it is stationary then it means the external force F and frcitional force F are equal

Let the value of that force be X

Now ,

W= F.S

= f.S. = X.S

here S is zero because it is not moving

W= X.0 = 0
