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)`
