Question

An object weighs 60 N when measured on the surface of the earth. Its weight on the surface of the Moon will be _______.
1. 10 N
2. 100 N
3. 360 N
4. 1 N

Answer 1

Correct Answer - Option 1 : 10 N

The correct answer is 10 N.

• The weight of the object on the surface of the moon will be 10 N.
• Given that
  • Weight of the object on the earth surface (W_e) = 60 N
  • sing the concept
  • Weight of the object on the moon \((Wm) = 1/6 * We\)
  • \(Wm = 1/6 * 60 = 10 N \)
  • An object weighs 60 N when measured on the surface of the earth.
  • Its weight on the surface of the Moon will be 10 N.

• The weight of an object on Earth and the Moon is different because Earth's gravity is much great than the Moon's gravity.
• Newton's law says that F=mg, where F is the weight and M is the mass, and G, is the acceleration due to gravity but since the gravity on Moon is much less than Earth.
• The weight of an object will be Different.
• The formula that links mass and the gravitational field strength is:
  • gravity force = mass × gravitational field strength (g)
• This is when:
  • gravity force is measured in newtons (N)
  • mass is measured in kilograms (kg)
  • gravitational field strength (g) is measured in newtons per kilogram (N/kg)
