A disc is rolling without slipping on a horizontal surface with C, as its centre and Q and P the two points equidistant from C. Let `v_(P),v_(Q) and v_(C)` be the magnitudes of velocities of point P,Q and C respectively, then

A

`v_(Q) gt v_(C) gt v_(P)`

B

`v_(Q) lt v_(C) lt v_(P)`

C

`v_(Q) = v_(P),v_(C) = (1)/(2) v_(P)`

D

`v_(Q) lt v_(C) gt v_(P)`

Text Solution
