Two bodies of masses $m_{1}=5 \mathrm{~kg} and m_{2}=3 \mathrm{~kg} are connected by a light string going over a smooth light pulley on a smooth inclined plane as shown in the figure. The system is at rest. The force exerted by the inclined plane on the body of mass \mathrm{m}_{1} will be : [Take \left.\mathrm{g}=10 \mathrm{~ms}^{-2}\right]
