what is a negative zero error?

Answer 1

When you measure some quantity by an instrument, if the instrument starts at less than zero. There is an error in the readings taken. This is NZE.

Answer 2

Negative error means positive zero correction.

Suppose we use a scale to measure the distance between two points A and B

We keep the scale such that the zero of the scale coincides with the point and note the reading at B.

The difference between the two readings is the distance AB

The reading of A being zero, the reading of B directly gives the value AB. No correction is needed here.

Suppose instead of keeping the Zero of the scale to coincide with A, we have made it to coincide with a point C in between A and B such that AC = 2 divisions, then the reading of B and hence the distance measured AB will be less by 2 divisions.

We add 2 divisions with the reading of B to get the correct distance of AB.

This type of correction is positive correction since we add 2 divisions to the reading of B.

The error involved here is negative zero error.

Answer 3

Negative zero error is a kind of error that happens frequently on vernier calipers. There is also positive zero error. Negative zero error is the error is when the zero mark is behind the real zero mark. (Normally, it is mm) Positive is when the zero mark is in front of the real zero mark. You can use the ruler to measure the zero error.

Answer 4

I'm wondering if you mean a "divide by zero" error. Division by zero is undefined; attempting to do this will create an error state in the operating system of a computer.

Answer 5

Zero isn't a negative numer.

Answer 6

zero is not anumber --it is a concept, that fills the void between positive and negitive---
