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

Options

A. `sqrt(2Mg)`
B. `sqrt(2mg)`
C. `(sqrt((M+m)^(2)+m^(2)))g`
D. `(sqrt((M+m)^(2)+M^(2)))g`

Explanation

`N^(2)=T^(2)+(mg+T)^(2)`
Put T= Mg
