MCQ

A sphere is released from rest on the incline having friction coefficient $\frac {1}{7}\,\,tan\,\theta $

A
it will start pure rolling
B
it will make pure translation motion
✓
it will start rolling with slipping
D
the angular momentum of the sphere about its centre will remain constnat

✓

Answer

Correct option: C.

it will start rolling with slipping

c
$\mu<\mu_{\min }\left(\mu_{\min }=2 / 7 \tan \theta\right)$

But $\mu \neq 0$

Therefore, sphere will roll with forward slipping.
