Question

A body having weight of 2kg at the surface of earth find the weight at h = 800km above the earths surface​

Answer 1

Answer:

Given,

         Weight=2 kg wt

         Than mass= 2kg

Than g'=g(1-$\frac{2h}{re}$)

        g'=g(1-(1-$\frac{1600}{6400}$)

        g'=g(1-$\frac{1}{4}$)

        g'=g($\frac{3}{4}$)

        g'=10*($\frac{3}{4}$)

        g'=2.5*3

        g'=7.5

Than weight of the object if it is 800 km above earths surface= mg'=2*7.5=15kg

Hence the weight will be 15 kg
