Question

A small block of mass 0.1kg lies on a fixed inclined plane PQ which makes an angle x with horizontal.A horizontal force of 1N on the block through its center of mass as shown The block remains stationary if

x = 45

x > 45 and friction acts towards p

x > 45 and friction acts towards Q

x < 45 and friction acts towards Q

Answer 1

x > 45 and friction acts towards Q

Answer 2

i will explain
