MCQ
Two particles are projected from the same point with the same speed at different angles $\theta _1$ and $\theta _2$ to the horizontal. They have the same range. Their times of flight are $t_1$ and $t_2$ respectively.
  • A
    ${\theta _1} = 90 - {\theta _2}$
  • B
    $\frac{{{t_1}}}{{\sin \,{\theta _1}}} = \frac{{{t_2}}}{{\sin \,{\theta _2}}}$
  • C
    $\frac{{{t_1}}}{{{t_2}}} = \tan \,{\theta _1}$
  • ✓
