Why must you use the same reference point b g h0 on the spring for each subsequent height measurement?

Question 2

A uniform electric field of 1.00 N/C is set up by a uniform distribution of charge in the xy plane. What is the electric field inside a metal ball placed 0.500 m above the xy plane?
1.1.00 N/C
2.21.00 N/C
3.0
4.0.250 N/C
5.varies depending on the position inside the ball

Answer to Question 1

The reference point for measuring the height above the table must be chosen in such
a way that elongation of the spring is the variable that is consistently measured. This
measurement may not be consistent if the masses vary in size or if the bottoms of the
masses are used as the height reference point.
