The acceleration due to gravity at a depth d below the surface of the earth is 20% of its value at the surface. What is the value of d if the radius of the earth=6400km ?

Find the expression of acceleration due to gravity at a depth d below the surface of the earth.

The acceleration due to gravity at a height h above the surface of the earth has the same value as that at depth d= ____below the earth surface.

Imagine Earth to be a solid sphere. If the value of acceleration due to gravity at a depth 'd' below Earth's surface is the same as its value at a height 'h' above its surface and is equal to g/4 then the ratio of h/d will be ......

The acceleration due to gravity at a height 1 km above the earth is the same sa at depth d below the surface of earth . Then

The acceleration due to gravity at a height 1 km above the earth is the same as at a depth d below the surface of earth

If .g. on the surface of the earth is 9.8 ms^(-2) , find its value at a depth of 3200km (radius of the earth = 6400km)

If g on the surface of the earth is 9.8 m//s^2 , its value at a depth of 3200km is (Radius of the earth =6400km ) is

If g is acceleration due to gravity at the surface of the earth, then its value at a depth of 1/4 of the radius of the earth is
