Two spherical planets P andQ have the same unfirom density $$\rho$$, masses $$M_P$$ and $$M_Q$$, an surface areas A and 4A, respectively. A spherical planet R also has unfirom density $$\rho$$ and its mass is $$(M_P + M_Q)$$. The escape velocities from the planets P, Q and R, are $$V_P, V_Q$$ and $$V$$ respectively. Then

A

$$V_Q > V_R > V_P$$

B

$$V_R > V_Q > V_P$$

C

$$\frac{V_R}{V_P} = 3$$

D

$$\frac{V_P}{V_Q} = \frac{1}{2}$$
