question 5

Multiple Choice

The mass of the Moon is $7.4 \times 10 ^ { 22 } \mathrm {~kg}$
its radius is $1.74 \times 10 ^ { 3 } \mathrm {~km}$
and it has no atmosphere. What is the acceleration due to gravity at the surface of the Moon? $\left( G = 6.67 \times 10 ^ { - 11 } \mathrm {~N} \cdot \mathrm { m } ^ { 2 } / \mathrm { kg } ^ { 2 } \right)$

• A) \(2.8 \times 10 ^ { 6 } \mathrm {~m} / \mathrm { s } ^ { 2 }\)
• B) \(4.9 \mathrm {~m} / \mathrm { s } ^ { 2 }\)
• C) \(1.6 \mathrm {~m} / \mathrm { s } ^ { 2 }\)
• D) \(0.80 \mathrm {~m} / \mathrm { s } ^ { 2 }\)
• E) \(9.8 \mathrm {~m} / \mathrm { s } ^ { 2 }\)
