A wheel of bicycle is rolling without slipping on a level road. The velocity of the centre of mass is v cm ; then true statement is :
Text Solution
Verified by ExpertsThe correct answer is:
A
For a body rolling without slipping , the velocity of any point P on the body is 
where 
= R ω in direction perpendicular to line joining centre and point P.
Velocity of point A is ,
v A = v cm + R ω
= v cm + v cm (v cm = R ω )
= 2v cm
velocity of point B is ,
v B = v cm – R ω
= v cm – v cm = 0
Thus, the velocity of point a is 2v cm and velocity of point B is zero.
