A string of negligible mass going over a clamped pulley of mass m supports a block of mass M as shown in the figure. The force on the pulley by the clamp is given by

A

`sqrt(2)Mg`

B

`sqrt(2)mg`

C

`(sqrt((M +m)^(2)+m^(2)))g`

D

`(sqrt((M +m)^(2)+M^(2)))g`

Text Solution

Verified by Experts

The correct Answer is:
d
Force on the pulley are
`F = sqrt(F_(1)^(2) + F_(2)^(2)) = (sqrt((m+M)^(2) +M^(2)))g`
