In the arrangement shown in the Fig, the ends P and Q of an unstretchable string move downwards with uniform speed U. Pulleys A and B are fixed.
Mass M moves upwards with a speed

A

`V cos theta`

B

`V // cos theta`

C

`2V cos theta`

D

`2//V cos theta`

Text Solution

Verified by Experts

The correct Answer is:
B
` U cos theta=V`
`therefore U=(v)/(cos theta)`
