Statement-I : Path of a projectile is a parabola irrespective of its velocity of projection.
Statement-II : Trajectory of a projectile is a parabola when variation of g, (acceleration due to gravity) can be neglected.

A

Statement-I is true, Statement-II is true, Statement-II is correct explanation for Statement-I

B

Statement-I is true, Statement-II is true, Statement-II is NOT a correct explanation for Statement-I

C

Statement-I is true, Statement-II is false

D

Statement-I is false, Statement-II is true.

Text Solution

Verified by Experts

The correct Answer is:
D
Whenever a particle having two `bot` components of velocity then the path of projectile will be parabolic if particle is projects vertically upwards then the path of projectile will be straight.
