The acceleration of light pulley is

A

F/m

B

F/2m

C

F/4 m

D

F/8 m

Text Solution

Verified by Experts

The correct Answer is:
C

Block: T=ma
`F=2TrArrT=F//2`
`a=(F)/(2m)`
If the block moves by a distance d, pulley moves by d/2
`a_(p)=(a)/(2)=(F)/(4m)`

In the situation shown in figure F=500 newton applied on the pulley m_(1)=50 kg and m_(2) = 10 kg and pulley and strings are massless and frictionless. Then the acceleration of the pulley is : [g = 10 m//s^(2)]

In the pulley system shown in figure the movable pulleys A, B and C are of 1 kg each D and E are fixed pulleys. The strings are light and inextensible find the accelerations of the pulleys and tension in the string.

String is wrapped over a pulley and free end is fixed to the ceiling as shown in figure. Mass of the pulley is m and its radius is R. Assume that pulley is identical to dise. Calculate acceleration of pulley as it is allowed to fall by unwinding the string. Assume that string does not slip over the pulley.

The acceleration of the light travelling in vacuum is ________

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