Dear Anurag,

Given:

Mass of the body = 2 kg

Angle of inclination with the horizontal = 30°

coefficient of static friction = 0.2

Case 1: The block is moving up on the inclined plane,

the force required to be applied up the plane to move the body,

substituting the given value we get, F = 13.464 N

Case 2: The block is moving down on the inclined plane,

the force on the body down the plane to move the body,

substituting the given value we get, F = 6.536N N
