The ratio of acceleration of pulley to t...

The ratio of acceleration of pulley to the acceleration of the block is (string is inextensible).

A

`0.5`

B

2

C

1

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
A
`x_(1)+x_(2)+l` implies `(dx_(1))/(dt)+(dx_(2))/(dt)=0`
`v_(P)-v_(B)=0`
`2v_(P)=v_(B)` . It gives `2a_(p)=a_(B)` implies `(a_(P))/(a_(B))=(1)/(2)` .

Find out the acceleration of the blocks and tensions in the strings.

Figure shows a block A constrained to slide along the inclined plane of the wedge B shown. Block A is attached with a string which passes through three ideal pulleys and connected to the wedge B. If wedge is pulled toward right with an acceleration a, find (a) the acceleration of the block with respect to wedge (b) the acceleration of the block with respect to ground.

A uniform chain of length 2L is hanging in equilibrium position, if end B is given a slightly downward displacement the imbalance causes an acceleration. Here pulley is small and smooth & string is inextensible The velocity v of the string when it slips out of the pulley (height of pulley from floor gt 2L)

If block B shown in figure-l.78(a) is going down with acceleration 5 m//s^(2) , find the acceleration of the block A. All pulleys and strings are ideal. Radii ratio for the two step pulleys are 1 : 3 : 5 and 1 :2 .

In the shown mass pulley system, pulleys and string are massless. The one end of the string is pulled by the force F = mg. The acceleration of the block will be :

A block of mass m is attached at the end of an inextensible string which is wound over a rough pulley of mass M and radius R figure a. Assume the stirng does not slide over the pulley. Find the acceleration of the block when released.

Consider the situation shown in the figure. The surface is smooth and the string and the pulley are light. Find the acceleration of each block and tension in the string.
