A body of mass m rests on a horizontal floor with which it has a coefficient of static friction `mu`. It is desired to make the body move by applying a minimum possible force `vecF` as shown in the diagram. The values of `theta` and `F_("min")` shall be respectively equal to

A

`theta = 0, F = mu W`

B

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

C

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

D

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