A uniform disc is performing pure rolling on a smooth stationary surface with constant angular velocity. At any instant, for the lower most point of the disc

a) velocity is V, acceleration is zero

b) velocity is zero, accleration is zero

c) velocity is V, accleration is $\large\frac{v^2}{R}$

d) velocity is zero, acceleration  is $ \large\frac{v^2}{R}$

Can you answer this question?

Since no force are acting , $a=0.$
$v=0$ , since it is rolling on a stationary surface
