Question

a body is released along a smooth inclined plane if it is moves with an uniform acceleration of g/2 then the angle of inclined plane is​

Answer 1

We see that the direction of acceleration is perpendicular to the base of incline (i.e. horizontal) and y-axis is perpendicular to theincline. Components of acceleration due to gravity The acceleration due to gravity forms an angle with y-axis, which is equal to angle ofincline.
