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 h1 and h2 respectively, then
\(\rm R=4 \sqrt{h_1 h_2} \).
Reason R: Product of said heights.
\(\rm h_1 h_2=\left(\frac{u^2 \sin ^2 \theta}{2 g}\right) .\left(\frac{u^2 \cos ^2 \theta}{2 g}\right) \)
Choose the correct answer :
1
Both A and R are true and R is the correct explanation of A.
2
Both A and R are true but R is NOT the correct explanation of A.
3
A is true but R is false.
4
A is false but R is true.
