A particle is projected from the ground ...

A particle is projected from the ground with velocity `u` at angle `theta` with horizontal. The horizontal rnage, maximum hieght and time of flight are `R,H` and `T` respectively. They are given by, `R = (u^(2)sin 2 theta)/(g),H = (u^(2)sin^(2)theta)/(2g)` and `T = (2usin theta)/(g)` Now keeping `u` as fixed, `theta` is varied from `30^(@)` to `60^(@)`. Then,

A

`R` will first increase then decrease, `H` will increase and `T` will decrease

B

`R` will first increase then decrease while `H` and `T` both will increase

C

`R` will decrease while `H` and `T` will increase

D

`R` will increase while `H` and `T` will increase
