What happens to weight at the center of the Earth? 📉
In this video, we solve a classic Class 9 Gravitation question: "The weight of an object at the centre of the earth of radius R is..."
The correct answer is Zero!
Here is why:
Weight depends on gravity (W = mg).
As you go deeper, gravity decreases.
At the center (d=R), gravity becomes zero because the earth's mass pulls you equally in all directions.
Topics Covered:
Variation of g with depth.
Difference between Mass and Weight.
