The gravitational field strength on the moon is [tex]\frac{1}{6}[/tex] of the gravitational field strength on the earth
On the earth:
the gravitational field strength (g) is determined as:
[tex]g=G\frac{m}{r^2}[/tex]
where:
[tex]g=9.8 N/kg = 9.8 m/s^2[/tex]
Then on the moon:
[tex]g=[tex]\frac{1}{6}[/tex]*9.8=1.6 N/kg[/tex]
The answer will be : A.1.6 N/kg
