Question

Assertion (A): In the motion of projectile the horizontal component of velocity remains constant

Reason (R) : The force on the projectile is the gravitational force which acts only in the vertically downward direction

• A. A and R are correct and R is the correct explanation of A
• B. A and R are correct and R is not the correct explanation of A
• C. A is true and R is false
• D. A is false and R is true

Answer 1

The correct option is A A and R are correct and R is the correct explanation of A

As the gravitational force acts downward a not any components of firce acts on the projectile in horizontal direction becuase of no horizontal force, the horizontal component of velocity has no change with time thus remains constant.

option A is correct.
