## Solution

Verified by Toppr

## Let be mass of the earth be the radius of the earth be gravitational acceleration at depth from the earth surface be gravitational acceleration on the earth surfaces be the density of the earth be the point inside the earth at depth from earth surfaces----------- since CS=R-------------- acceleration due to gravity at depth -----------Dividing eq by eq
