Acceleration Due to Gravity
Given below are two statements: One is labelled as Assertion A and the other is labelled as Reason R.
Assertion A: If we move from poles to equator, the direction of acceleration due to gravity of earth always points towards the center of earth without any variation in its magnitude. Reason R: At equator, the direction of acceleration due to the gravity is towards the center of earth. In the light of above statements, choose the correct answer from the options given below:
Show answer and solution
Answer: (d)
- A is false: due to rotation, changes in magnitude from pole to equator () and does not point exactly to the centre at other latitudes.
- R is true: at the equator the centrifugal term is along the radius, so effective points to the centre.
- So the answer is (d).
