Question 5: Laws of Motion

Question

A body of mass 5 kg is suspended by a spring
balance on an inclined plane as shown in
figure.
So, force applied on spring balance is

Accepted Answer

Acceleration of the body down the rough inclined plane $$=g \sin 	heta$$
$$	herefore$$ Force applied on spring balance
$$\begin{aligned}
& =m g \sin 	heta=5 	imes 10 	imes \sin 30^{\circ} \\
& =5 	imes 10 	imes \frac{1}{2}=25 \mathrm{~N}
\end{aligned}$$
