In figure, the string has a mass of 14 kg. How much time will it take for a transverse disturbance produced at fixed support to reach the pulley?

A

0.91sec

B

1.20sec

C

1.59 sec

D

2.35 sec

Text Solution

Verified by Experts

The correct Answer is:
A
The value of tenstion force near the pulley in the rope will be the value at all the points of horizontal part of rope.
`T=6g=60N` [from F.B.D. of hanging part of rope]
`therefore V=sqrt((T)/(mu))=sqrt((60)/(2))=sqrt(30)`
`therefore`Required time `t=(5)/(V)=(5)/(sqrt(30))=0.91sec`.
