Discuss the variation of g with altitude.

Discuss the variation of g with height and depth.

What do you understand by 'g'. Discuss the variation of g with rotation of earth after establishing a relation for the same.

Variations

Obtain an expression for the acceleration due to gravity on the surface of the earth in terms of mass of the earth and its radius. Discuss the variation of acceleration due to gravity with altitude and depth. If a body is taken to a height R / 4 from the surface of the earth, find percentage decrease in the weight of the body ? Here R is the radius of the earth.
