Question

If a body of mass m is taken to the bottom of a deep mine, then its ___.

• A. mass increases
• B. mass decreases
• C. weight increases
• D. weight decreases

Answer 1

The correct option is D weight decreases

The value of acceleration due to gravity is maximum at the surface of the earth. It decreases with increase in height from the surface. It also decreases with increase in depth from the surface. Hence, it is lower in the mine.

Since weight is the product of mass and acceleration due to gravity, it also decreases in a mine.
