Question

A block is kept on a frictionless inclined surface with angle of inclination α. The incline is given an acceleration a to keep the block stationary. Then find a

Answer 1

$\huge\red{Answer}$

M is the mass of the small block. The force is in the direction of acceleration

a

as shown in the fig. The force F should be such that the block remains in equilibrium.

Therefore, for equilibrium maCosα = mgSinα

a= gtanα
