Question

At what height from earth
surface, the acceleration due to
grauity will be half the value
of g on surface.(R=6400km)​

Answer 1

At what height from the surface of earth will the value of g be reduced by 36% from the value on the surface? Take radius of earth R=6400km. Solution : Since the acceleration due to gravity reduces by 36% the value of acceleration due to gravity there is 100-36=64%.
