Question

A body of mass 9 kg is lying on a surface of a table, Calculate the net force acting on it.
​

Answer 1

Explanation:

For moving the body, applied force should be greater or equal to limiting friction tie, N). The limiting friction is

(a) Since, applied force F = 5 N, so body starts to move in forward direction.

(b) Here, applied force is lesser than limiting friction. So, body does not move.

( c) The reason is same as (
