MCQ
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 $R = \frac{{{u^2}\sin 2\theta }}{g}$, $H = \frac{{{u^2}{{\sin }^2}\theta }}{{2g}}$ and $T = \frac{{2u\sin \theta }}{g}$ Now keeping $u $ as fixed, $\theta$ is varied from $30^o$ to $60^o$. Then,
- A$R$ will first increase then decrease, $H$ will increase and $T$ will decrease
- ✓$R$ 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
