Question

a body of mass 100 g is made just to slide on rough surface by applying a force of 0.8 N .Then find coefficient of friction.​

Answer 1

Answer

If μ be the coefficient of friction, the friction force f=μmg

As the friction force opposes the motion, so in equilibrium, the friction force is equal to the applying force.

So, μmg=0.8 or μ=

(0.1)(10)

0.8

=0.8=8×10

−1

Thus, the value of x is 1.
