150 \times 10^6 \text{km}

respectively. Their masses are

8 \times 10^{22} \text{kg}

2 \times 10^{30}

kg respectively. The radius of the earth is 6400 km. Let

\Delta F_1

be the difference in the forces exerted by the moon at the nearest and farthest points on the earth and

\Delta F_2

be the difference in the force exerted by the sun at the nearest and farthest points on the earth. Then, the number closest to
