The student notices that the electronic balance has a zero error, so it shows mass readings that are all slightly too small. This means that the density value is incorrect and slightly too small. The correct option is B.
What is density?
The density is the ratio of the mass and the volume of the object. It is denoted by ρ.
ρ = mass/Volume = m/V
The student notices that the electronic balance has a zero error, so it shows mass readings that are all slightly too small.
As mass is directly proportional to density. The density will also be slight small when mass reading are all slightly small.
Thus, the correct option is B.
