Question

varietion of g due to depth

Answer 1

Variation of g with depth. Assuming the earth to be a homogenous sphere (having uniform density) of radius R and mass M. Let ρ be the mean density of earth. Let a body be lying on the surface of earth where the value of acceleration due to gravity is "g". ... The percentage decrease in the value of g is 100.

hope it helps u (:

Answer 2

where R= radius of earth
g=9.8m/s²
x= depth
.
if u need the derivation of this than tell me
