Question

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.
A. If both the assertion and reason are true and reason is a true explantion of the assertion.
B. If both the assertion and reason are true but the reason is not true the correct explantion of the assertion.
C. If the assertion is true but reason false
D. If both the assertion and reason are false.

Answer 1

Correct Answer - C
Up to ordinary heights, the change in the distance of a projectile form the centre of earth is negligible compared to the raduis 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, the path of the projectile becomes elliptical.
