Question
Which of the following graphs shows the correct variation of acceleration due to gravity with the height above the earth's surface?
A.
B.
C.
D.
None of these
Answer :
Solution :
Acceleration due to gravity with height $$h$$ varies as $$g \propto \frac{1}{{{r^2}}}$$
(when $$r = R + h$$ ). Thus variation of $$g$$ and $$r$$ is a parabolic curve.
