1.

Assertion: For projection angle `tan^(-1)(4)`, the horizontal range and the maximum height of a projectile are equal. Reason: The maximum range of projectile is directely proportional to square of velocity and inversely proportional to acceleration due to gravity.A. If both Asseration and Reason are correct and Reason is the correct explanation of AssertionB. If both Assertion and Reason are correct but Reason is not the correct explanation of AssertionC. If Assertion is true but Reason is falseD. If Assertion is false but Reason is true

Answer» Correct Answer - B
`H = R` or `(u^(2)sin^(2)theta)/(2g) = (2u^(2)sin theta cos theta)/(g)` or `tan theta = 4`
