Question:

On the Moon, the force of gravity on an object is only about one-sixth of its value on Earth. Decide whether each of the following would give an accurate measurement of the mass if used on the Moon

a) A beam balance like the one in the diagram at the top of the page

b) A balance like the one in the photograph above. (please note the balance the question refers to is a modern type of balance- electronic one)My understanding is that a beam balance compares weight and on the moon the weight of the object changes not the mass. Since a beam balance compares weight, on the moon if an object's weight changes thus it will not be able to give the accurate reading for mass.

Therefore for (a) i said no it will not give a accurate reading for mass

However, for (b) i said yes it will give an accurate reading of mass because according to the notes i am reading from the modern type of balance detects gravitational pull but gives the reading in units of mass.

However according to the book, I was wrong.

The book answers states that (a) gives a more accurate reading of mass

(b) does not

Please can someone help me understand why?I attached a modern balance so everyone understand what type of modern balance i am talking about
