Two block of masses $7\ kg$ and $5\ kg$ are placed in contact with each other on a smooth surface. If a force of $6\ N$ is applied on the heavier mass, the force on the lighter mass is [image:5_image11.png]

Question

Dr. Abubacker · Accepted Answer

(b) Newton second law
$F = ma \Rightarrow 6 = (7 + 5)a\ ;a = \frac{1}{2}\frac{m}{s^{2}};F' ightarrow 5\ kg$
Now, $F^{'} = 5 	imes \frac{1}{2} = 2.5\ N$
