Question

Draw graphs of showing the variation acceleration due to gravity with



height above the earth's surface and


depth below the earth's surface.

Answer 1

Answer:

(a)The variation of g with height h is related by relation g∝ 1/r2 where r=R+h. Thus, the variation of g and r is a parabolic curve.

(b)The variation of g with depth is released by equation g’=g(1-d/R) i.e. g’ ∝ (R-d) Thus, the variation of g and d
