When a projectile is projected in oblique motion expressions for time

1.	When a projectile is projected in oblique motion expressions for time of flight andrange of the projectile are given . Which of the following pairis correct ?
Answer» `t_(F) = (u sin THETA)/(2G):R = (u^(2) sin 2 theta)/(2g)` `t_(f) = (2u sin theta)/(g):R = (u^(2) sin 2 theta)/(g)` `t_(f) = (2u costheta)/(g):R = (u^(2) COS2 theta)/(g)` `t_(f) = (2u sin theta)/(g):R = (u^(2) sin2 theta)/(2g)` Answer :B
