Question

A body has a weight of 10 kg on the surface of earth.What will be it's weights when taken to the centre of the earth

Answer 1

Since it is completely impossible with current technology to actually do this as a real experiment, I will assume we are talking totally theoretically.

Mass is an inherent property of the object. As long as you take the whole 10 kg object and don’t lose any parts on the way, it should still be a 10 kg object at the end of the trip.

Weight is also referred to as the force of gravity and it depends on location. We can use a type of mathematics called calculus to show the exact relationship between the weight and how far we are from the surface of the Earth. As you move inside a solid body like a planet, it turns out that the overall gravity depends on how much mass of the planet is further inside than you are. When you get to the very center, the overall gravity is zero.

Answer 2

✯ Weight will be 0 ✯

Explanation:

Given:

• Weight of the body on the surface of earth is 10 kg. (m) = 10 kg
• Acceleration due to gravity (g) = 0

To Find:

• What will the weight of body when it is taken to the centre of the earth?

Solution: Since, g = 0 at the centre of the earth.

$we \: know \: that \: = weight(f) = m \times g$

$f \: = \: m \times g \\ f = 10 \times 0 \\ f = 0$
