A body weighs 72 kg on the surface of the earth its weights on the surface of the moon will be:
Correct answer: B. 12kg
- A. 72 kg
- B. 12kg
- C. 24 kg
- D. 0kg
Explanation
The weight of an object on the surface of the moon can be calculated using the formula:Weight on the moon = Weight on the Earth× (Acceleration due to gravity on the moon / Acceleration due to gravity on the Earth)The acceleration due to gravity on the moon is about 1/6th of that on Earth.Weight on the moon = 72kg × (⅙)= 12kgTherefore, the weight of the body on the surface of the moon will be 12kg.

About Law of Universal Gravitation
Every two masses attract each other with a force proportional to the product of their masses and inversely proportional to the square of their separation, expressed as F = Gm₁m₂/r². Questions also involve the gravitational constant, vector direction, superposition of gravitational forces, and the distinction between gravitational force and gravitational field strength.
