Two particles are projected with the same initial velocity, one makes an angle $$\theta$$ with the horizontal while the other makes an angle $$\theta$$ 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. $$R^{0}$$

A particle $$(A)$$ is dropped from a height and another particle $$(B)$$ is projected in a horizontal direction with a speed of $$5$$ m/s from the same height. The correct statement, from the following, is:

 1 Particle $$(A)$$ will reach the ground first with respect to particle $$(B)$$. 2 Particle $$(B)$$ will reach the ground first with respect to particle $$(A)$$. 3 Both particles will reach the ground at the same time. 4 Both particles will reach the ground at the same speed.
