The correct Answer is:
To solve the question, we need to analyze both the assertion and the reason provided. ### Step 1: Analyze the Assertion The assertion states that collisions between two billiard balls are inelastic. - **Explanation**: Billiard balls are not perfectly elastic bodies. In a perfectly elastic collision, both momentum and kinetic energy are conserved. However, in the case of billiard balls, some kinetic energy is lost during the collision due to deformation and sound, which indicates that the collision is inelastic. **Conclusion**: The assertion is true. ### Step 2: Analyze the Reason The reason given is that momentum remains conserved during the collision. - **Explanation**: According to the law of conservation of momentum, the total momentum of a closed system remains constant before and after a collision, regardless of whether the collision is elastic or inelastic. Therefore, momentum is conserved in all types of collisions. **Conclusion**: The reason is also true. ### Step 3: Determine the Relationship Now we need to determine if the reason correctly explains the assertion. - **Explanation**: While both the assertion and the reason are true, the reason does not explain why billiard balls undergo inelastic collisions. The conservation of momentum applies to all collisions, not just inelastic ones. The reason does not address the loss of kinetic energy that characterizes inelastic collisions. ### Final Conclusion Both the assertion and the reason are true, but the reason is not the correct explanation of the assertion. **Answer**: Option B: Both assertion and reason are true, but the reason is not the correct explanation of the assertion. ---
