A wooden box lying at rest on an inclined surface of a wet wood is held at static equilibrium by a constant force `vec F` applied perpendicular to the incline. If the mass of the box is 1 kg, the angle of inclination is `30^(@)` and the coefficient of static friction between the box and the inclined plane is `0.2,` the minimum magnitude of `vecF` is (Use `g= 10m//s^(2))`

Options

A. `0 N, as 30^(@)` is less than angle of repose
B. `ge 1N`
C. `ge 3.3N`
D. `ge16.3N`

Answer

D
