Two bodies of masses $m_{1} = 5 k g$ and $m_{2} = 3 k g$ 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 $m_{1}$ will be : [Take $g = 10 m s^{- 2}$ ]

Answer:

Solution:

Equilibrium: $m_{2} g = m_{1} g sin θ \Rightarrow sin θ = \frac{3}{5}, cos θ = \frac{4}{5}$ .

$N = m_{1} g cos θ = 5 \times 10 \times \frac{4}{5} = 40 N$ - (B).
