AIIMS 2009 Physics Projectile Motion Assertion Reason Question
Type: Assertion Reason-conceptual-Medium-Class 11
Assertion : Generally the path of a projectile from the earth is parabolic but it is elliptical for projectiles going to a 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.
A
Both Assertion and Reason are true and Reason is the correct explanation of Assertion.
B
Both Assertion and Reason are true but Reason is not the correct explanation of Assertion.
C
Assertion is true but Reason is false.
D
Both Assertion and Reason are false.
