question 15

Multiple Choice

At their closest approach, Venus and Earth are $4.20 \times 10^{10}$ $10^{24} \mathrm {~kg} ,$ the mass of Earth is $5.97 \times 10 ^ { 24 } \mathrm {~kg}$ and $G = 6.67 \times 10 ^ { - 11 } \mathrm {~N} \cdot \mathrm { m } ^ { 2 } / \mathrm { kg } ^ { 2 }$ What is the magnitude of the gravitational force exerted by Venus on Earth at that point?

• A) \(6.30 \times 10 ^ { 20 } \mathrm {~N}\)
• B) \(1.72 \times 10 ^ { 19 } \mathrm {~N}\)
• C) \(4.62 \times 10 ^ { 28 } \mathrm {~N}\)
• D) \(5.43 \times 10 ^ { 26 } \mathrm {~N}\)
• E) \(1.10 \times 10 ^ { 18 } \mathrm {~N}\)
