Question

When a body having mass 'M' is placed at the centre of earth, its weight will be:

• A. M
• B. Zero
• C. 2M
• D. M

Answer 1

Answer:

B. Zero

• Gravitational Force: The attraction between two bodies is proportional to the product of their masses and inversely proportional to the square of their distance.
• A body positioned at the earth's center has no weight.
• This is due to the fact that the mass of the earth is zero at its most accurate center. Only when an item has mass does gravitational force exist
