In the figure, the disc D does not slip ...

In the figure, the disc `D` does not slip on the surface `S`, the pulley `P` has mass and the string does not slip on it. The string is wound around the disc.

A

The acceleration of the block `B` is double the acceleration of the centre of `D`

B

the force of friction exerted by `D` on `S` acts to the left

C

the horizontal and the vertical sections of the string has the same tension

D

the sum of the kinetic energies of `D` and `B` is less than the loss in the potential energy of `B` as it moves down

Text Solution

Verified by Experts

The correct Answer is:
A, B, D
According to the given figure `V_(B)=2V_(disc).....(1)`
After taking derivative a_(B)=2a_(disc)` here `b` & `d` are conceptual

A uniform solid cylinder of mass M and radius 2R rests on a horizontal table top. A string attached to it runs over a pulley (disc) of mass M and radius R thatis mounted on a frictionless axle through its centre. A block of mass M is suspended from the free end of the string. The string doesn't slip over the pulley surface, and the cylinder rolls without slipping on the, table top. Find the acceleration of the block. [g/3]
