Solve by difficulty
EASYTwo bodies of masses $\mathrm{m}_1=5 \mathrm{~kg}$ and $\mathrm{m}_2=3 \mathrm{~kg}$ 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 $\mathrm{g}=10 \mathrm{~ms}^{-2}$ ]
Assertion: One mass of 10 kg is there in an inclined plane of 30 degrees and is attached with a vertically hanging mass of 20 kg by a string; which passes over a smooth pulley; acceleration of the system is
Reason: acceleration of the system is

Double inclined plane with different angles
$\begin{aligned} & a=\frac{\left(m_2 \sin \theta_2-m_1 \sin \theta_1\right) g}{m_1+m_2} \\ & T=\frac{m_1 m_2\left(\sin \theta_1+\sin \theta_2\right) g}{m_1+m_2}\end{aligned}$
