The period of revolution of planet A around the sun is 8 times that of planet B. How many times the distance of A from the sun is greater than that of B from the sun?

Options:

Answer:

Solution:

$(\frac{R _{1}}{R _{2}})^{3} = (\frac{T _{1}}{T _{2}})^{2} = (8)^{2} = 64 ∴ \frac{R _{1}}{R _{2}} = (64)^{\frac{1}{3}} = 4 ∴ R_{1} = 4 R_{2} ∴ R_{1} - R_{2} = 4 R_{2} - R_{2} = 3 R_{2}$
