Correct option is C
We know thatR=u2sin2θg and hmax=u2sin2θ2gGiven that R=hmax∴ u2sin2θg=u2sin2θ2g or 2sinθcosθ=sin2θ/2 or tanθ=4 or θ=tan−1(4)Similar Questions
Assertion : When the velocity of projection of a body is made n times, its time of flight becomes n times.
Reason : Range of projectile does not depend on the initial velocity of a body.
