Given below are two statements : one is labelled as Assertion \(A\) and the other is labelled as Reason \(R\). Assertion \(A\) : When a body is projected at an angle \(45^{\circ}\), it's range is maximum. Reason \(R\) : For maximum range, the value of \(\sin 2 \theta\) should be equal to one. In the light of the above statements, choose the correct answer from the options given below :
Pick an option to check your answer.
Answer & Solution
Correct Answer
(B) Both \(A\) and \(R\) are correct \(R\) is the correct explanation of \(A\)
Step-by-step Solution
Detailed explanation
\(R =\frac{ u ^2}{ g } \sin 2 \theta\)
\(R\) is maximum for \(2 \theta=90^{\circ}\).
