Question

The mass of the Moon is 7.3x1022 kg and its radius is 1738 km. What is the strength of the gravitational field on the

surface of the Moon? (Do all required steps)

Answer 1

1.61 N/kg

Step-by-step explanation:

Take the universal gravitational constant G as 6.67 × 10^(-11) Nm²/kg²

The required gravitational field strength

= 6.67 × 10^(-11) × 7.3 × 10^(22) / (1738000)²

= 1.61194103 N/kg

= 1.61 N/kg (corr. to 3 sig. fig.)
