A particle is projected from the ground with velocity `u` at angle `theta` with horizontal.The horizontal range,maximum height and time of flight are `R,H` and `T` respectively.Now keeping `u` as fixed, `theta` is varied from `30^(@)` to `60^(@)`.ThenA. `R` will first increase.`H` will increase and `T` will decreaseB. `R` will first increase.than decrease while `H` and `T` both will increaseC. `R` will decrease while `H` and `T` will increaseD. `R` will increase while `H` and `T` will decrease |
|
Answer» Correct Answer - B `R prop sin 2 theta,H prop sin^(2) theta` and `T prop sin theta,sin 2theta` will first increase, then decrease.While `sin theta` will only increase. |
