A disc is rolling (without slipping) on a horizontal surface. C is its centre and Q and P are two points equidistant from C . Let v P ,  v Q and v C be the magnitude of velocities of points P, Q and C respectively, then

Options:

Answer:
A
Solution:

In case of pure rolling bottommost point is the instantaneous centre of zero velocity.

Velocity of any point on the disc, v=r ω, where r is the distance of point from O.



r Q > r C > r P

∴   v Q > v C > v P
