NEET Physics Question - Kinematics - Ground to Ground Projectile

Assertion (A): Path of a projected ball is parabolic in uniform gravitational field for oblique projection in absence of air resistance.

Reason (R): Gravitational force is always act perpendicular to velocity during the motion of a projectile.

(1) Both (A) & (R) are true and the (R) is the correct explanation of the (A)

(2) Both (A) & (R) are true but the (R) is not the correct explanation of the (A)

(3) (A) is true but (R) is false

(4) Both (A) and (R) are false

Solution:

Assertion (A) is true because projectile motion under gravity without air resistance follows a parabolic path.

Reason (R) is false as gravitational force acts perpendicular to velocity only at the peak of the trajectory, not always. Thus, (A) is true, (R) is false.
