How gravitational acceleration changes according to depth?

Gravitational acceleration on the surface of a planet is (sqrt(6)//11) g, where g is the gravitational acceleration on the surface of the earth. The average mass density of the planet is 2/3 times that of the earth. If the escape speed on the surface of the earth is taken to be 11 km*s^(-1) , the escape speed on the surface of the planet in km*s^(-1) will be

Gravitational force is

The value of gravitational acceleration____

If G is universal gravitational constant and g is acceleration due to gravity then the unit of the quantity G/g is

Acceleration due to gravity decreases as we go below the surface of the earth. What will be the nature of the graph between the change of acceleration due to gravity and the depth below the surface of the earth ?

On what other factor does the pressure at a point in a liquid depend besides the depth of that point and the acceleration due to gravity at that place?

Derive an expression for acceleration due to gravity at a depth d from earth's surface . Is it increases or decreases.

The force of gravitation between two spherical masses M and m, placed in air, is F . The space between the two spheres is filled with a liquid of relative density 3. What will be the change in the value of the gravitational force acting between the spheres ?
