Explanation:
- Assertion: At the centre of earth, a body has a centre of mass but no centre of gravity.
- Reason: Acceleration due to gravity at the centre of the earth is zero.
Both the assertion and reason are true. However, the reason is the correct explanation of the assertion. This can be understood as follows:
- Centre of mass: It is the point where the entire mass of an object can be considered to be concentrated.
- Centre of gravity: It is the point where the entire weight of an object can be considered to be concentrated.
- At the centre of the earth, the body experiences gravitational forces from all directions. However, the gravitational forces from all directions cancel out each other at the centre of the earth.
- Therefore, the acceleration due to gravity at the centre of the earth is zero.
- As the weight of a body is the product of its mass and acceleration due to gravity, the weight of the body becomes zero at the centre of the earth.
- Thus, at the centre of the earth, a body has a centre of mass but no centre of gravity.
Hence, both assertion and reason are true and reason is the correct explanation of the assertion.
