In the given figure, a solid sphres is placed on a plank having acceleration `a_(0)` (shown in the figure). Then,
`(BIT_PHY_C08_E01_047_S01.png" width="80%">

Options

A. if `a_(p)=a_(0)`, then pure rolling takes place
B. if `v_(p) = v_(0)`, then pure rolling takes place
C. if `a_(p) =a_(0)`, `v_(p)nev_(0)`, then pure rolling takes place
D. if `a_(p) = a_(0)` , `v_(p) = v_(0)` then pure rolling takes place

Explanation

d) For pure rolling motion, the relative motion between point of contact and surace should be zero.
This is possible only when, `a_(p) =a_(0), v_(p) =v_(0)`
