When a projectile is projected in oblique motion expressions for time of flight and range of the projectile are given .
Which of the following pair is correct ?

Options

A. `t_(f) = (u sin theta)/(2g):R = (u^(2) sin 2 theta)/(2g)`
B. `t_(f) = (2u sin theta)/(g):R = (u^(2) sin 2 theta)/(g)`
C. `t_(f) = (2u cos theta)/(g):R = (u^(2) cos2 theta)/(g)`
D. `t_(f) = (2u sin theta)/(g):R = (u^(2) sin2 theta)/(2g)`

Answer

B
