Question

explain why the value of g changes from poles to equator on the surface of the earth. state how its value changed on moving:

1) towards the centre of the earth

2)away from the earth?

Answer 1

the value of g changes from equator the poles because as we know the earth is bulging from the equator and g is inversely proportional to the r hence value of g decreases as we move from the equator to the poles

1]when we move from earths surface to words the center the value of g decreases

2]when we move away from the surface it again decreases
