Let, ge be the acceleration due to gravity on surface of earth, g′ be the acceleration due to gravity at depth d below the surface of earth and is given by
g′=ge(1−d/R) ............................(1)
The acceleration due to gravity of an object on latitude(below the surface of earth) is
g′=ge−ω2Rcosϕ
where, ϕ is the solid angle at the centre of earth sustained by the object.
At the equator, ϕ=0∘
∴cosϕ=1
Hence,
g′=ge−ω2R ...............(2)
From (1) and (2), we can write
ge(1−d/R)=ge−ω2R
⇒dge=ω2R
⇒d= ω2R2/ ge
g′=ge(1−d/R) ............................(1)
