The horizontal range covered by projectile is proportional to

(A): The maximum horizontal range of projectile is proportional to square of velocity. (R): The maximum horizontal range of projectile is equal to maximum height at tained by projectile

(A): The maximum horizontal range of projectile is proportional to square of velocity. (R): The maximum horizontal range of projectile is equal to maximum height at tained by projectile

Assertion: The maximum horizontal range of projectile is proportional to square of velocity. Reason: The maximum horizontal range of projectile is equal to maximum height attained by projectile.

The horizontal range for projectile is given by

Write the equation for the horizontal range covered by a projectile and specify when it will be maximum .
