Assertion: The value of acceleration due to gravity changes with the height, depth and shape of the earth.
Reason: Acceleration due to gravity is zero at the centre of the earth.
The correct answer is option 'B' - Both assertion and reason are true but the reason is not the correct explanation of the assertion.
Explanation:
Gravity is the force of attraction between two objects with mass. The acceleration due to gravity is the acceleration experienced by an object in free fall near the surface of a massive body, such as the Earth.
Assertion: The value of acceleration due to gravity changes with the height, depth and shape of the earth.
This assertion is true. The acceleration due to gravity is not constant throughout the Earth. It varies with height, depth, and shape of the Earth.
1. Height: As we move away from the surface of the Earth, the distance between the object and the center of the Earth increases. This leads to a decrease in the acceleration due to gravity. So, the value of acceleration due to gravity decreases with increasing height.
2. Depth: When an object is below the surface of the Earth, the mass of the Earth above the object attracts it in all directions. This leads to a decrease in the acceleration due to gravity. So, the value of acceleration due to gravity decreases with increasing depth.
3. Shape: The shape of the Earth also affects the acceleration due to gravity. The Earth is not a perfect sphere, it is slightly flattened at the poles and bulges at the equator. This shape variation causes the acceleration due to gravity to be slightly different at different locations on the Earth's surface.
Reason: Acceleration due to gravity is zero at the center of the earth.
This reason is not the correct explanation of the assertion. The acceleration due to gravity is not zero at the center of the Earth. In fact, it is at its maximum value at the center of the Earth. At the center, the gravitational forces from all the mass around cancel out, resulting in a net gravitational force of zero. However, the acceleration due to gravity is defined as the force on a unit mass. Since the force is zero at the center, the acceleration is also zero. But it is important to note that this is a special case at the center and not applicable to other points within the Earth.
Reason: Acceleration due to gravity is zero at the centre of the earth.
The correct answer is option 'B' - Both assertion and reason are true but the reason is not the correct explanation of the assertion.
