There can't be a negative zero. zero is neither negative nor positive.
Suppose say you have plastic rule new one. There you will be having zero marking. When you have to measure the length of a rod then you would keep zero marking at one end of the rod and the marking where the other extreme of the rod is taken to be length of the rod. say it is at 4 cm. So 4cm is the length. And suppose the ruler is an old one whose edge got damaged. Now you don't have zero marking so visible there. So you have keep the end of the rod at say 1 cm marking. Now the error that we commit is known as zero error. Here the error is positive. ie +1 cm. So as the other end of the rod is at 5cm marking then the correct length is got by applying zero correction. As zero error is +1 cm, then zero correction would be -1 cm So the correct length 5-1 ie 4 cm. Same way in case of vernier, if zero of vernier is at left side of zero of main scale, then the zero error is negative. If zero of vernier is right side of zero of main scale then error is +ve as we have seen in the earlier old ruler case. Same way in case of screw gauge as the head scale zero is above pitch line then error is negative and as head scale zero is below pitch line then zero error is positive.
Zero is not negative. It is not positive either.Zero is not negative. It is not positive either.Zero is not negative. It is not positive either.Zero is not negative. It is not positive either.
Take a measurement with nothing in the gauge. That reading is the zero-error.
Zero is neither positive or negative.
if the zero of vernier scale lies on the right side of the zero of the main scale , then error is known as a positive error .
There can't be a negative zero. zero is neither negative nor positive.
There is no negative zero or positive zero, zero is just zero so you can take it off. For example: 3-2-0= just 3-2
zerro error in a spring balance affects the accuracy in the weight. To find zero error in spring balance, you have to first find the least count of the spring balance and then suspend it freely, if the outcome is +1, the zero error is +1 and if it is -1 ,the zero error is -1.
The zero error of a screw gauge is the error that occurs when the zero mark of the thimble does not align perfectly with the reference line of the sleeve. This error can lead to incorrect measurements as it affects the starting point of measurement. It is important to calibrate and adjust the screw gauge to eliminate zero error.
It is a defect in a measuring device (Vernier Callipers & Screw Gauge) & zero error is caused by an incorrect position of the zero point.
we can find the zero error by closing the jaw of screw guage if the zero of main scale(MS) is concide with the zero of circular scale (CS) there is no zero error and if they are not concide there is a zero error in screw guage .
The zero error of vernier calliper is defined as :-The zero error is equal to the distance between the zero of the main scale and the zero of the vernier scale.

When I type any number divided by zero into my calculator, it flashes, "ERROR, ERROR," but I say it's possible. "It's not possible to divide by zero," my math teacher says, but who cares about her? Here's my data after graphing it out: If any positive number is divided by zero, it's infinity, if it's negative, it's negative infinity, and zero divided by zero is one. NO NO, you cannot divide by zero, really. See my discussion post.
