Radii and densities of two planets are $$R_1, R_2$$ and $$\rho_1, \rho_2$$ respectively. The ratio of accelerations due to gravity on their surfaces is:
1. $$\frac{\rho_1}{R_1}:\frac{\rho_2}{R_2}$$
2. $$\frac{\rho_1}{R^2_1}: \frac{\rho_2}{R^2_2}$$
3. $$\rho_1 R_1 : \rho_2R_2$$
4. $$\frac{1}{\rho_1R_1}:\frac{1}{\rho_2R_2}$$

Imagine a new planet having the same density as that of the Earth but $$3$$ times bigger than the Earth in size. If the acceleration due to gravity on the surface of the earth is $$g$$ and that on the surface of the new planet is $$g'$$, then:
 1 $$g' = 3g$$ 2 $$g' = 9g$$ 3 $$g' = \frac{g}{9}$$ 4 $$g' = 27g$$
