Question

PLS HELP! What is the gravitational field strength on the moon?

A. 1.6 N/kg
B. 10 N/kg
C. 1.6 N

Answer 1

The gravitational field strength on the moon is
`(1)/(6)` of the gravitational field strength on the earth

On the earth:

the gravitational field strength (g) is determined as:

`g=G(m)/(r^2)`

where:

• G: the gravitational constant
• m: the mass of the earth
• r: the radius of the earth

`g=9.8 N/kg = 9.8 m/s^2`

Then on the moon:

`g=[tex](1)/(6)`*9.8=1.6 N/kg[/tex]

The answer will be : A.1.6 N/kg
