Tangent of angle of friction is equal to
Right Answer is:
Coefficient of friction
The angle of repose is the least angle of the inclined plane (of the given surface) with the horizontal such that the given body placed over the plane, just begins to slide down, without getting accelerated.
The tangent of the angle of repose is equal to the coefficient of friction.
Hence, we conclude that the angle of friction (θ) is equal to the angle of repose (φ).
