Question

variation of g with depth

Answer 1

g = 9.8 in earth
So
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.
