Take the mean distances of the Moon and the Sun from Earth to be

0.4\times10^6\text{ km}

and

150\times10^6\text{ km}

, respectively. Their masses are

8\times10^{22}\text{ kg}

and

2\times10^{30}\text{ kg}

, respectively. Let

\delta F_1

be the difference in the forces exerted by the Moon at the nearest and farthest points on Earth, and let

\delta F_2

be the corresponding difference due to the Sun. The number closest to

\frac{\delta F_1}{\delta F_2}

is: (1)

2

(2)

6

(3)

10^{-2}

(4)

0.6
