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. 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,

Options

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 increases
C. R will decrease while H and T both will increase
D. R will increase while H and T both will also increase

Answer

B
