George observed a difference in measurements for the same item at different altitudes due to variation in gravity.


Which type of scale did he likely use?

Aanalytical scale
BSpring scale
CBalance

Verified Answer :

George used the spring scale. For example: Using a spring scale on an elevator. As you go either up a floor or down a floor the gravity will change the outcome of the scale's measurements.

Answer:

B) Spring scale

Explanation:

As we the altitude changes the gravity's effect on body will change and it will affect the weight of the person too! Because,

\(w = m \times g\)

where, w = weight of the object

m = mass of the object

g = acceleration due to gravity

This difference will only be seen when you will use a spring scale as the object is directly being pulled by the Earth and the impact will only be in the object. Whereas, In other scales the impact of the change in gravity will be same on both measuring weight and the objects so the weight variation will not be seen.
