Question 11

Multiple Choice

The Moon (mass 7.35×1022 kg7.35 \times 10^{22} \mathrm{~kg} ) orbits the Earth (mass 5.98×1024 kg5.98 \times 10^{24} \mathrm{~kg} ) at a distance of 3.85×1083.85 \times 10^{8} meters. Meanwhile, the Earth orbits the Sun (mass 1.99×1030 kg1.99 \times 1030 \mathrm{~kg} ) at a distance of 1.50×10111.50 \times 1011 meters. When the Moon is directly between the Earth and the Sun, what is the gravitational field at the location of the Moon due to the Earth and the Sun combined? (G=6.67×1011 N m2/kg2) \left(\mathrm{G}=6.67 \times 10-11 \mathrm{~N} \mathrm{~m}^{2} / \mathrm{kg}^{2}\right)


A) 3.21×103 N/kg3.21 \times 10^{-3} \mathrm{~N} / \mathrm{kg} toward the Sun
B) 3.21×103 N/kg3.21 \times 10^{-3} \mathrm{~N} / \mathrm{kg} toward the Earth
C) 5.93×103 N/kg5.93 \times 10^{-3} \mathrm{~N} / \mathrm{kg} toward the Sun
D) 2.69×103 N/kg2.69 \times 10-3 \mathrm{~N} / \mathrm{kg} toward the Earth
E) 5.93×103 N/kg5.93 \times 10^{-3} \mathrm{~N} / \mathrm{kg} toward the Earth
