A blocky of mass m rests on a horizotal floor with which it has a coefficient of static friction `mu.` It is desired to make the body move by applying the minimum possible force F. Find the magnitude of F and the direction in which it has be applies.

A

`theta=tan^(-1)(mu),F=(muW)/(sqrt(1+mu^(2)))`

B

`theta=tan^(-1)((1)/(mu)),F=(muW)/(sqrt(1+mu^(2)))`

C

`theta=0,F=muW`

D

`theta=tan^(-1)((mu)/(1+mu)),F=(muW)/(1+mu)`
