Connected Bodies & Pulleys

Two blocks of masses 6 kg and 4 kg are placed in contact with each other on a smooth surface as shown. If a force of 5 N is applied on a heavier block, the force on the lighter block is

Show answer and solution

Answer: (c)

Common acceleration: $a = \dfrac{F}{m_1 + m_2} = \dfrac{5}{6 + 4} = 0.5\text{ m/s}^2$ .
The 4 kg block is pushed only by the contact force: $N = 4 \times 0.5 = 2\text{ N}$ .
So the answer is (c) 2 N.
