Two particles are projected from the same point with the same speed at different angles `theta_(1)` and `theta_(2)` to the horizontal. If their respective times of flights are `T_(1)` and `T_(2)` and horizontal ranges are same then
a) `theta_(1)+theta_(2)=90^(@)` ,
b)`T_(1) =T_(2)tan theta_(1)`
c.`T_(1) =T_(2)tan theta_(2)` ,
d) `T_(1)sin theta_(2)=T_(2)sin theta_(1)`

Options

A. `theta_(1) +theta_(2) = 90^(@)`
B. `(t_(1))/(t_(2)) = tan theta_(1)`
C. `(t_(1))/(t_(2)) = tan theta_(2)`
D. `(t_(1))/(sin theta_(1)) = (t_(2))/(sin theta_(2))`

Answer

A, B, D
