The figure shows a fixed incline plane on which a plank is being pulled upwards such that the centre C of the solid cylinder remains at rest with respect to ground. If no slipping takes place between the cylinder and the plank, then the acceleration of the plank is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
2g sin 
Linear acceleration of cylinder is zero, i.e.,
mg sin 
= f ( here f = frictional force upwards )
Angular acceleration about the centre 
or 
or 
For no slipping between cylinder and plank
