Question

The weight of a body is lesser inside the mine than on the surface of earth why?

A) Due to the absence of gravity inside the mine
B) Because of the difference in air pressure
C) Due to the presence of minerals in the mine
D) It's an optical illusion

Answer 1

The weight of a body is lesser inside the mine than on the surface of Earth because weight depends on the acceleration due to gravity.

Step-by-step explanation:

The weight of a body is lesser inside the mine than on the surface of Earth because weight depends on the acceleration due to gravity. When an object enters a region with weaker gravity, such as inside a mine, it will weigh less.

For example, the acceleration due to gravity on the Moon is much weaker than on Earth, so an object would weigh less on the Moon compared to the Earth, even if its mass remains the same.

This is because weight is a measure of the force of gravity acting on an object, and when gravity is weaker, the force is less and therefore the weight is less.
