A body weighs 300 ~N on the surface of the earth. How much will it weigh at a distance R 2 below the surface of earth? ( R Radius of earth)

Step-by-step solution

Acceleration due to gravity at depth d , aligned g _ d & = g (1- d R ) & = g (1- 1 2 ) d = R 2 & = g 2 aligned Weight of the body at depth d ₁ W _ d = mg _ d =300 1 2 =150 ~N
