A smooth wedge A is fitted in a chamber hanging from a fixed ceiling near the earth's surface.A block B placed at the top of the wedge takes a time T to slide down the length of the wedge. If the block is placed at the top of the wedge and the cable supporting the chamber is broken at the same instant, the block will

A

take a time longer than T to slide down the wedge

B

take a time shorter than T to slide down the wedge

C

remain at the top of the wedge

D

jump off the wedge

Text Solution

Verified by Experts

A smooth wedge A is fitted in a chamber hanging from a fixed ceiling near the erth's surface.A block B placed at the top of the wedge takes a time T to side down the length of the wedge. If the block is placed at the top of the wedge and the cable supporting the chamber is broken at the same instant, the block will

All surfaces are smooth Find the horizontal displacements of the block and the wedge when the block slides down from top to bottom .

In figure, the pulley shown is smooth. The spring and the string are light. Block B slides down from the top along the fixed rough wedge of inclination theta . Assuming that the block reaches the end of the wedge, find the speed of the block at the end. Take the coefficient of friction between the block and the wedge to be mu and that the spring was relaxed when the block was released from the top of the wedge.

In the figure shown the pulley is smooth . The spring and the string are light. The block 'B' slides down from the top along the fixed rought wedge of inclination theta . Assuming that the block reaches the end of the wedge. Find the speed of the block at the end. Take the coefficient of friction between the block and the wedge to be mu and the spring was relaxed when the block was relased from the top of the wedge.

A block of mass m is placed on a smooth wedge of wedge angle theta The whole system is accelerated horizontally so that the block does not slip on the wedge. The force (normal reaction) exerted by the wedge on the block has a magnitude:

A wedge with mass M rests on a frictionless horizontal surface A block with mass m is placed on the wedge. There is no friction between the block and the wedge. A horizontal force f is applied to the wedge. What magnitude F must have if the block is to remain at constant height above the table top?

A block of mass m is placed on a smooth wedge of inclination theta & mass M. The whole system is slip on the wedge. Then the normal reaction on the wedge acting from the ground :

A block of mass m is placed on the inclined sufrace of a wedge as shown in fig. Calculate the acceleration of the wedge and the block when the block is released. Assume all surfaces are frictionless.

A wooden wedge of mass 10 m has a smooth groove on its inclined surface. The groove is in shape of quarter of a circle of radius R = 0.55 m . The inclined face makes an angle theta =cos^(-1)((sqrt(11))/(5)) with the horizontal A block 'A' of mass m is palced at the top of the groove and given a gentle push so as to slide along the groove. There is no friction between the wedge and the horizontal ground on which it has been placed. Neglect width of the groove. (a) Find the magnitude of displacement of the wedge by the instant the block A reaches the bottom of the groove (b) Find the velocity of a wedge at the instant the block A reaches the bottom of the groove.

A block of mass m is placed on a smooth wedge of incination theta . The whole system s acelerated horizontally so tht the block does not slip on the wedge. The force exerted by the wedge on the block has a magnitude
