    Radius of earth is around 6000 km. The weight of body at height of 6000 km from earth surface becomes [RPMT 1997]

    A) Half    

    B)             One-fourth

    C)             One third        

    D)             No change

    Correct Answer: B

    Solution :

                    \[g'=g{{\left( \frac{R}{R+h} \right)}^{2}}\]Þ when \[h=R\] then \[g'=\frac{g}{4}\] So the weight of the body at this height will become one-fourth.
