Question

A cylinder of mass 10 kg and radius 15 cm is rolling perfectly on a plane of inclination 30° and length 1 m . If the coefficient of static friction is μ =0.25 , then the work done against friction during rolling is (A) 0 (B) (25 √3/2)J (C) (50 √3/2) J (D) (75 √3/2)J

The work done by friction force in case of pure rolling is always zero because the point of application of friction force doesn't slip

Q. A cylinder of mass $10 k g$ and radius $15 c m$ is rolling perfectly on a plane of inclination $3 0^{\circ}$ and length $1 m$ . If the coefficient of static friction is $μ = 0.25$ , then the work done against friction during rolling is

0
