हिन्दीA horizontal force \( 10\text{ N} \) is applied to a block A as shown in figure. The mass of blocks A and B are \( 2\text{ kg} \) and \( 3\text{ kg} \), respectively. The blocks slide over a frictionless surface. The force exerted by block A on block B is:
Correct answer · Option 1
6 N
Explanation
Acceleration of the system \( a = \frac{F}{m_A + m_B} = \frac{10}{2 + 3} = 2\text{ m/s}^2 \). The contact force exerted on B by A is \( F_{AB} = m_B \cdot a = 3 \times 2 = 6\text{ N} \).
