When a body resting on an inclined surface just begins to slide down the inclined plane under the action of its own weight, then the angle of inclination of the inclined plane is

When a body resting on an inclined surface just begins to slide down the inclined plane under the action of its own weight, then the angle of inclination of the inclined plane is Correct Answer Greater than the angle of repose

Explanation:

The angle of repose or angle of sliding (α)
  • It is defined as the minimum angle of inclination of a plane with the horizontal such that a body placed on the plane just begins to slide down.
  • Its value depends on the material and nature of the surface in contact. 
​
  • If the angle of inclination of plane = Angle of repose: A body is in equilibrium on a rough inclined plane under its own weight.
  • If the angle of inclination of plane > Angle of repose: A body resting on an inclined surface just begins to slide down the inclined plane under the action of its own weight.
  • If the angle of inclination of plane < Angle of repose: A body resting on an inclined surface does not move down the inclined plane under the action of its own weight.
