Question 9

Gravitational Field

An object of weight 80kg on earth is taken to a planet where the acceleration due to gravity is one-third of its value on earth. The weight of the object on the planet is [g=10 ms−2]

  1. A.12 N.
  2. B.27 N.
  3. C.36 N.
  4. D.48 N.
Show the answer and explanation

Answer: B (27 N.)

Explanation

Weight is proportional to g, so on the planet the weight is one-third of its earth value: 80 ÷ 3 ≈ 27 N.
