Sticky Note
The weight of an object at the center of the earth of radius R is ______?
رداس آر کی زمین کے مرکز میں کسی چیز کا وزن ______ ہے؟
  1. Rise a little
  2. Weightless
  3. Same
  4. None of these
Explanation

The weight of an object at the center of the Earth is the same as its weight on the surface.

This might seem counterintuitive, but it's because the gravitational force acting on the object is proportional to the distance from the center of the Earth.

At the center, the distance is zero, but the gravitational force is also zero because the object is surrounded by equal amounts of mass in all directions.
