Two particles are projected with the same initial velocity, one makes an angle θ with the horizontal while the other makes an angle θ with the vertical. If their common range is R, then the product of their time of flight is directly proportional to:
1.  R
2.  ${R}^{2}$
3.  $\frac{1}{R}$
4.  ${R}^{0}$
