Question

Which is true concerning the acceleration due to Earth's gravity (ge) ? It decreases with increasing altitude. B. It is different for different objects in free fall. C. It is a fundamental quantity. D. It increases with increasing altitude. E. all of these

Answer 1

Answer:

Option A decreases with increase in altitude

Explanation:

This can be explained as the value of gravitational acceleration, 'g' is not same everywhere.

It has its maximum value at poles of the Earth and minimum on its equator.

Thus a person will weigh more at poles than equator.

This variation is in accordance to:

$g = \frac{GM_{E}}{radius^{2}}$

Thus the gravitational acceleration changes as inverse square of the Radius of the Earth.

Thus as we move away from the Earth's center, gravitational acceleration, g decreases.
