Question

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.

• A. If both Assertion and Reason are true and the Reason is the correct explanation of the Assertion.
• B. If both Assertion and Reason are true but the Reason is not the correct explanation of the Assertion.
• C. If Assertion is true but Reason is false.
• D. If both Assertion and Reason are false.

Answer 1

Answer: (C)

Upto ordinary heights, the change in the distance of a projectile from the centre 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 decreasing variable force, the path of the projectile becomes elliptical.
