Given below are two statements. One is labelled as Assertion A and the other is labelled as Reason R.
Assertion A: Two identical balls A and B thrown with same velocity ’u’ at two different angles with horizontal attained the same range R. If A and B reached the maximum height

{h_1}

and

{h_2}

respectively, then

R = 4\sqrt {{h_1}{h_2}}

Reason R: Product of said heights.

{h_1}{h_2} = \left( {\frac{{{u^2}{{\sin }^2}\theta }}{{2g}}} \right).\left( {\frac{{{u^2}{{\cos }^2}\theta }}{{2g}}} \right)

Choose the correct answer:

Correct option: A

Both A and R are true and R is the correct explanation of A

Option A is correct because both the assertion and reason are true, and the reason correctly explains the assertion.
