The axis of the uniform cylinder in figu...

The axis of the uniform cylinder in figure is fixed. The cylinder is initially at rest. The block of mass M is initially moving to the friction and with speed `v_(1)`. It passes over the cylinder to the dashed position. When it first makes contact with the cylinder, it slips on the cylinder, but the friciton is large enough so that slipping ceases before M loses contacts wtih the cylinder. the cylinder has a radius R and a rotaitonal intertia I

Assertion : Momentum of the block -cylinder system is conserved
Reason: Force of friction between block and cylinder is internal force of block -cylinder system.

A

If both (A) and (R) are true and (R) is the correct explanation of (A)

B

If both (A) and (R) are true but (R) is not correct explanation

C

(if (A) is true but (R) is false

D

IF (A) is false and (R) is true

Text Solution

Verified by Experts

The correct Answer is:
D
Assertion is false as hinge applier some force on the block cylinder system

A uniform disc of mass M and radius R is initially at rest. Its axis is fixed through O. A block of mass m is moving with speed v_(1) on a frictionless surface passes over the disc to the dotted position. On coming in contact with the disc, it slips on it. The slipping ceases before the block loses contact with the disc, due to the high friction. Now, the velocity of mass m is

A clockwise torque of 6N-m is applied to the circular cylinder as shown in the figure. There is no friction between the cylinder and the block.

In the figure the plank resting on two cylinders is horizontal. The plank is pulled to the right such that the centre of smaller cylinder moves with a constant velocity v . Friction is large enough to prevent slipping at all surfaces. Find- (a) The velocity of the centre of larger cylinder. (b) The ratio of accelerations of the points of contact of the two cylinders with the plank.

A uniform cylinder of mass m lies on a fixed plane inclined at a angle theta with the horizontal. A light string is tied to the cylinder at the rightmost point, and a mass m hangs from the string as shown. Assume that the coefficient of friction between the cylinder and the incline plane is sufficiently large to prevent slipping. for the cylinder to remain static the value of m is
