Assertion: The height attained by a pro...

Assertion: The height attained by a projectile is twenty five percentage of range, when projected for maximum range.
Reason: The height is independent of initial velocity of projetile.

A

If both the assertion and reason are true and reason is a true explantion of the assertion.

B

If both the assertion and reason are true but the reason is not true the correct explantion of the assertion.

C

If the assertion is true but reason false

D

If both the assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
c
Range will be maximum when `theta=45^(@)` and in this conditions `R=4H implies R//4` (always)because `R=4H cot theta and theta=45^(@)`
So maximum height is `25%` of maximum range. It does not depends upon the velocity of projetion.
