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

Answer 1

Force on pulley by the camp=resultant of $T=(m+m)g$ and $mg$ acting along horizontal and vertical directions respectively$F=\sqrt{{\left[\right(M+m\left)g\right]}^2+{\left(mg\right)}^2}$

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