Physics - NLM Question with Solution | TestHub

Two blocks of masses 3 kg and 7 kg are at rest on the ground. The masses are connected by a massless string passing over a smooth and light pulley. A 300 N force is applied on the pulley. The difference in acceleration of blocks in $\mathrm{m}/{\mathrm{s}}^2$ is $\frac{50\sqrt{\mathrm{x}}}{7}$. Find x .
