A body of mass m is kept on a rough horizontal surface (coefficient of friction= μ). A horizontal force is applied to the body, but it does not move. The resultant of normal reaction and the frictional force acting on the object is given by F, where:

1. |F|=mg+μmg

2. |F|=μmg

3. |F|mg1+μ2

4. |F|=mg
