Question

The variation of acceleration due to gravity (g) with distance (r) from the center of the earth is correctly represented by
(Given R = radius of earth)

• A.
• B.
• C.
• D.

Answer 1

Answer: (A)

Answer 2

For $r < R$
$g = \frac{Gmr}{R^3} = Cr$ (C=Constant)
For $r > R$
$g = \frac{Gm}{R^2} = \frac{C}{r^2}$ $(C =Constant)$

So, for the above equations the best suited graph is as given in option (A)
