Question

A zero error occurs when an instrument
Options
A has a worn-out scale.
B gives a non-zero reading when the true reading should be zero.
Correct Answer
C is used at an incorrect angle.
D gives fluctuating readings.
Correct Answer

Option B is the correct answer.

Detailed Explanation

Zero error is a specific type of systematic error. It occurs when the instrument does not read zero when it should, such as a mass scale showing 0.200 g when nothing is on it. This introduces a fixed error into all subsequent readings.

Hint

This error is identified by checking the instrument's reading when it is supposed to measure a zero quantity.
