Question 7

Gravitational Field

The force experienced by an object of mass 60.0kg in the moon's gravitational field is 1.002 × 102 N. What is the intensity of the gravitational field?

  1. A.0.60 N kg−1
  2. B.1.67 N kg−1
  3. C.6.12 × 102 N kg−1
  4. D.9.81 m s−2
Show the answer and explanation

Answer: B (1.67 N kg−1)

Explanation

Field intensity = force per unit mass = 100.2 ÷ 60.0 = 1.67 N kg−1.
