Question

Calculate the value of the universal gravitational constant from the following mass data mass of earth = 6 = 10²⁴ kg radius of earth = 6400 km and the acceleration due to gravity on the surface of the earth = 9.8 m/s²​

Answer 1

Answer:

g=GM/R²

gR²=GM

G=gR²/M

  =9.8x6400²/6x10^24

  ≈6.67x10^-11
