To explain why the path of a projectile is parabolic at ordinary heights and elliptical at great heights, we can break down the explanation into several steps: ### Step-by-Step Solution: 1. **Understanding Projectile Motion**: - At ordinary heights (where the height \( h \) is much less than the radius of the Earth \( R \)), the motion of a projectile can be approximated using the equations of motion under constant acceleration due to gravity \( g \). 2. **Condition for Parabolic Path**: ...

Assertion : Generally the path of a projectile from the earth is parabolic but it is elliptical for projectiles going to very great height. Reason : Up to ordinary height the projectile moves under a uniform gravitational force, but for great heights, projectile moves under a variable force.

Assertion: Generally the path of projectile form the earth is parabolic but it is elliptical for projection going to a very large height. Reason: The path of projectile is independent of the gravitational force of earth.
