Write down the variation of the acceleration due to gravity at a point above the surface of the earth to the square of the distance of that point from the centre of the earth.

What is the value of the acceleration due to gravity on the surface of the earth ?

What is the value of the acceleration due to gravity at the centre of the earth ?

The acceleration due to gravity at a height R ( radius of the earth ) from the earth' s surface is

what is the value of acceleration due to gravity at the centre of the earth ?

The acceleration due to gravity at a height above the earth's surface is ……..than that at the same depth below the surface of the earth. [Fill in the blanks]

What will be the value of the acceleration due to gravity at a point 3 km above the earth's surface ? Diameter of the earth =12800 km and g=980cm*s^(-2) on the surface of the earth.

Where on the surface of the earth is the value of g least due to the diurnal motion of the earth ?

Draw the graph of variation of acceleraton due to gravity with the depth and height from the surface of the earth, assuming that the density of earth is costant.

The ratio of the mass of the moon to that of the earth is 1:81. If the radius of the moon is assumed to be one-fourth of that of the earth , then what is the acceleration due to gravity on the surface of the moon in terms of that on the earth's surface ? Hence, find the escape velocity from the surface of the moon in terms of that from the earth's surface.
