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

Answer

D

Explanation

By (1) and (2)
`F_("net")=(sqrt((M+m)^(2)+M^(2)))g`
`because" Pulley at rest, "`
`therefore" Force on the pulley by the champ having magnitude equal to "F_("net")` but in opposite direction:.
