The weight of a body at the centre of the earth is

• A. Zero
• B. Infinite
• C. Same as on the surface of earth
• D. None of the above

The weight of a body at the center of the Earth is a fascinating topic in physics. At this point, the gravitational forces from all directions cancel each other out.

Understanding Weight at the Earth's Center

When considering the options:

• A. Zero: This is correct because the gravitational pull is neutralized.
• B. Infinite: This is incorrect; weight cannot be infinite.
• C. Same as on the surface of Earth: This is also incorrect; weight changes with location.
• D. None of the above: This option does not apply since option A is correct.

Final Answer

The correct answer is A. Zero. At the center of the Earth, a body experiences no weight due to the equal gravitational pull from all sides.
