Question

A sphere can roll on a surface inclined at an angle θ if the friction coefficient is more than 27g tanθ. Suppose the friction coefficient is 17g tanθ. If a sphere is released from rest on the incline,
(a) it will stay at rest
(b) it will make pure translational motion
(c) it will translate and rotate about the centre
(d) the angular momentum of the sphere about its centre will remain constant.

Answer 1

Answer:

ans is b

Explanation:

if hear required coefficient of friction is 27 g tan tera for pure rolling and translational motion and it was given coefficient of friction 17g tan teta

means it will not perform rolling motion and it will perform only translational motion

hope so ki mera ans right hoga
