The acceleration due to gravity on the Moon is (1/6) of that on the Earth. Hence, an object weighing 12 N on the Earth will weigh ________ on the Moon.
2 N
Concept:
- Acceleration due to gravity: The acceleration experienced by an object due to the gravitational force exerted by the Earth is referred to as acceleration due to gravity.
- Since each planet has different mass and radius, the acceleration due to gravity will vary for different planets.
- Weight: The weight (w) of an object is the force of gravity acting on it and can be defined as the product of gravitational acceleration (g) and mass (m)
- Weight is a force, and the SI unit of weight is Newton.
Weight (W) = m g
Where m is mass and g is acceleration due to gravity.
- The mass of the moon is 1/100th that of the Earth and the radius of the moon is 1/4th that of the Earth.
- Since the acceleration due to gravity on the moon is one-sixth that of the Earth's gravitational acceleration.
- The weight of an object on the moon = 1/6 × weight of an object on the Earth's surface
Explanation:
It is given that:
The weight of any object on the Earth's surface is 12 N
The weight of an object on the moon = 1/6 × weight of an object on the Earth's surface = 12 × 1/6 = 2 N
So option 3 is correct.
