Physics - NLM Question with Solution | TestHub

Two blocks of mass $\mathrm{m}=5\mathrm{kg}\&\mathrm{M}=10\mathrm{kg}$ are connected by a string passing over a pulley B as shown. Another string connects the centre of pulley B to the floor and passes over another pulley A as shown. An upward force $\mathrm{F}=300\mathrm{N}$ is applied at the centre of A. [Both pulley are ideal \& massless \& $\mathrm{g}=10\mathrm{m}/{\sec }^2$ :-
