Draw graphs showing the variation of accleeration due to gravity with (a) height above the Earth's surface, (b) depth below the Earth's surface.

Text Solution

Verified by Experts


(a) `g. = g(1-(d)/(R ))`
or `g. prop (R-d)`
The graph of g versus depth d will be a straight line shown by AB.
(b) `g prop (1)/((R+h)^(2))`
As `g prop (1)/(r^(2))`
The graph of g versus r is a parabolic curve.
