Question

Zero error of an instrument introduces,

Answer 1

Zero error is the error in the instruments which shows inaccurate value.there are two types of error 1.Positive error.
2Negative error
Example of positive error
Suppose their is weigh balance and it has error +0.1 kg and a person weighs 40.1 then to get the actual value we should subtract 40.1 -0.1 which is only equal to 40 kg
Example of Negative error
Suppose there is error of -0.1 kg and a person weighs 39.9 then we have to add 0.1 to 39.9 which is equal to 40kg

Hope this helps you

Answer 2

The systematic error is known as zero error.

Explanation:

• Random mistakes in experimental measurements are caused by unknown and unanticipated changes in the experiment.
• The measuring instruments are frequently the source of systematic mistakes in experimental observations.
• As the name implies, a zero error is one that has a relationship to the zero mark on a scale.
• In a practical lab, determining the magnitude of the mistake and then subtracting it from the reading with the error to obtain the real reading is critical.

Errors can be of two types:

• Random
• Systematic errors

Random error:

A random error is a disparity in observed and true values of something that happens by chance.

Systematic error:

A constant or proportional disparity between the observed and real values of anything is referred to as systematic error.
