Question : The weight of a body at the centre of the earth is:
Option 1: Half the weight at the surface
Option 2: Zero
Option 3: Twice the weight at the surface
Option 4: Infinite
Correct Answer: Zero
Solution : The answer is Zero .
The weight of a body at the earth's core is zero because the acceleration due to gravity (g) is equal to 0. As we move towards the equator's centre, the acceleration caused by gravity decreases to zero from its highest point on the planet's surface.
