A body of mass m rests on a horizontal rough platform. Coefficient of static friction is u. Calculate the minimum possible force required to move the body along the platform.

Text Solution

Verified by Experts


`:.` Force of friction `= mu_s m g`
This force is needed to start moving the body`implies F gt mu _s` mg Fshould be just greater than the force of static friction and the most effective force is a horizontal force.
