Question

A sphere of mass M and radius R is released from the top of an inclined plane of inclination θ . The minimum coefficient of friction between the plane and the sphere so that it rolls down the plane without sliding is given by, μ = tan ⁡ θ, μ = 2 3 tan ⁡ θ, μ = 2 5 tan ⁡ θ, μ = 2 7 tan ⁡ θ

MARKS App · Accepted Answer

μ ≥ tan ⁡ θ 1 + R 2 K 2 ⇒ μ min = tan ⁡ θ 1 + R 2 K 2
