The correct Answer is:
To solve the question, we need to analyze both statements provided: ### Step 1: Analyze Statement 1 **Statement 1**: "A particle is thrown by a man from the ground. Minimum speed of the particle in the subsequent motion may not be zero. (Air resistance is neglected)." - When a particle is thrown upwards, it will rise to a certain height and then come to a stop momentarily at its peak height before falling back down. - At the peak height, the speed of the particle is zero. After reaching the peak, it will start to fall back down, gaining speed due to gravity. - Therefore, the minimum speed of the particle during its motion is indeed zero (at the peak). **Conclusion for Statement 1**: This statement is **false**. ### Step 2: Analyze Statement 2 **Statement 2**: "Acceleration of the particle is never zero during the motion of the particle." - The only force acting on the particle (neglecting air resistance) is gravity, which provides a constant acceleration downwards, denoted as \( g \). - This acceleration acts on the particle throughout its entire motion, both when it is moving upwards and when it is falling downwards. **Conclusion for Statement 2**: This statement is **true**. ### Final Conclusion - **Statement 1** is false because the particle does reach a minimum speed of zero at its peak. - **Statement 2** is true because the acceleration due to gravity is always present. ### Final Answer - Statement 1 is false, and Statement 2 is true. ---
