Question

calculate the value of g on the surface of moon if mass=7.4×10^22kg and radius=1.75×10^6m
​

Answer 1

Answer:

g = 1.611

Explanation:

Mass of moon is, M = 7.4 × $10^{22}$ kg  

Radius of moon is, R = 1.75 × $10^{6}$ m  

Acceleration due to gravity of moon is, g = GM/$R^{2}$

we know that,

G is the universal gravitational constant, G = 6.67 × $10^{-11}$  $m^{3}$ $kg^{-1}$$s^{-2}$

=> g = (6.67 × $10^{-11}$)(7.4 × $10^{22}$)/(1.75 × $10^{6}$ $)^{2}$

=> g = 1.611
