Explanation:
The acceleration due to gravity on a body decreases with depth.
Acceleration due to gravity is the change in velocity with time of a body as result of the pull of gravity or gravitational force.
- The acceleration due to gravity tend to pull all bodies to the center of the earth.
- As body moves away from the center of the earth, the pull becomes very more and acceleration increase.
- But when a body approaches the center of the earth, the acceleration reduces.
- At depth, the acceleration due to body of a body begins to decrease.
