When a body is placed on a rough plane inclined at an angle $\theta $ to the horizontal, its acceleration is

A

$g(\sin \theta - \cos \theta )$

B

$g(\sin \theta + \mu \cos \theta )$

C

$g(\mu \sin \theta  - \cos \theta )$

D

$g\mu (\sin \theta - \cos \theta )$

When a body is placed on a rough plane inclined at an angle $\theta $ to the horizontal, its acceleration is

$F_{\min }=M g \sin \theta+\mu m g \cos \theta=m g(\sin \theta+\mu \cos \theta)$

Therefore acceleration is given by

$A=g(\sin \theta+\mu \cos \theta)$
