Question

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.
• B.
• C.
• D.

Answer 1

The correct option is D

Force on the pulley by the clamp

$F_{pc}=\sqrt{T^2+\left[\right(M+m)g{]}^2}$
$F_{pc}=\sqrt{(Mg{)}^2+[(M+m)g{]}^2}$
$F_{pc}=\sqrt{M^2+(M+m{)}^2}g$
