The correct Answer is:
To analyze the given statements, let's break down the problem step by step: ### Step 1: Understand Statement-I **Statement-I**: "The path of a projectile is a parabola irrespective of its velocity of projection." - A projectile's motion consists of two components: horizontal and vertical. - The path is a parabola only when both components are present (i.e., when the projectile is launched at an angle). - If a projectile is launched vertically (with no horizontal component), it will not trace a parabolic path; instead, it will move straight up and then straight down. **Conclusion**: Statement-I is **false**. ### Step 2: Understand Statement-II **Statement-II**: "The trajectory of a projectile is a parabola when the variation of g (acceleration due to gravity) can be neglected." - The trajectory of a projectile is indeed a parabola when the acceleration due to gravity (g) is constant. - If we consider the motion of a projectile near the Earth's surface, g can be assumed constant for small heights. In this case, the projectile's motion can be modeled as a parabolic trajectory. - If g varies significantly (e.g., at very high altitudes), the trajectory may not be a perfect parabola. **Conclusion**: Statement-II is **true**. ### Final Conclusion - Statement-I is **false**. - Statement-II is **true**. - Since Statement-II provides a correct explanation for the conditions under which Statement-I might be true, we conclude that Statement-I is false and Statement-II is true. ### Summary - **Statement-I**: False - **Statement-II**: True
