Acceleration of Block on Smooth Inclined Plane

When an Inclined Plane is at rest

$R=mg\:cos\theta$ along with normal to the incline

$mg\:sin\theta =ma$ along the incline

$a=g\:sin\theta$

When an Inclined Plane is given Acceleration 'b'

$R=mg \:cos\theta +mb\:sin\theta$

$ma= mg\:sin\theta -mb\:cos\theta$

$a=g\:sin\theta -b\:cos\theta$

$\ast$ Condition for the body to be at rest relative to the inclined plane.

$a=g\:sin\theta -b\:cos\theta =0$

$b=g\:tan\theta$
