The universal gravitational constant is measured experimentally using Cavendish s experiment This experiment is a very precise experiment which gives the value of G as 6 6742 0 0010 x 10 11 N m2 kg2 Since the universal gravitational constant has some error in it using it if we find escape speed and acceleration due to gravity on Earth s surface our values will have error in it Assume mass of Earth 6 0000 x 1024 kg radius of Earth 6 4000 10 m The measurement of mass of Earth has an error of 0 01 and radius of Earth has an error of 0 02 What will be the maximum percentage error in calculating the escape speed on earth
