Question

The variation of acceleration due to gravity $g$ with distance $d$ from centre of the earth is best represented by (R = Earth?s radius) :

• A.
• B.
• C.
• D.

Answer 1

Answer: (D)

Answer 2

Variation of g inside earth surface
$d < R = g = \frac{Gm}{R^{2}} .d$
$d=R =g_{s} = \frac{Gm}{R^{2}}$
$d > R = g = \frac{Gm}{d^{2}}$
