In this question, a statement of assertion 
is followed by a statement of reason (R). Mark the correct choice as:
Assertion: Generally the path of a projectile from the earth is parabolic but it is elliptical for projectiles going to a very large height.
Reason: The path of a projectile is independent of the gravitational force of earth.
Text Solution
Verified by ExpertsC
Upto ordinary heights, the change in the distance of a projectile from the center of earth is
negligible compared to the radius of earth. Hence the projectile moves under a nearly uniform gravitational force and the path is parabolic. But for the projectiles moving to a large height the gravitational force decreases quite rapidly (as 
). Under such a rapidly decreasing variable force, the path of the projectile becomes elliptical.
