A 10 kg block is placed on a horizontal surface whose coefficient of friction is 0.2.A horizontal force P = 15 N first acts on it in the eastward direction. Later, in addition to P a second horizontal force Q = 20 N acts on it in the northward direction: (Take `g= 10m/s^(2)`)

Options

A. The block will not move when only P acts, but will move when both P and Q act.
B. If the block moves,the acceleration will be `0.5 m/s^(2)`.
C. When the block moves, its direction of motion will be `tan^(-1)(3/4)` east of north
D. When both P and Q act, the direction of the force of friction acting on the block will be `tan^(-1)(3/4)` west of south

Answer

A, B, C
