অভিকর্ষজ ত্বরণ g এর পরিবর্তন

Let 'gh{ g }_{ h }' and 'gd{ g }_{ d }' be the acceleration due to gravity at height 'hh' above the earth's surface and at depth 'dd' below the earth's surface respectively. IF gh=gd{ g }_{ h }={ g }_{ d } then the relation between 'hh' and 'dd' is

Let the radius of the earth be R

and acceleration due to gravity at earth surface be g.

Acceleration due to gravity at height h

above the earth surface, g”=g(1−2h/R)

A

cceleration due to gravity at depth d

below the earth surface, g’=g(1−d/R)

Now for g”=g’

we get, g(1−2h/R)=g(1−d/R)

1−2h/R=1−d/R

d=2h
