If the zero of the vernier scale lies on the right hand of the zero marking of the main scale. Negative zero error: if the zero of the vernier scale lies on the left side of the marking of the main scale. Least count: Least count of a measuring i s the least value of the physical quantity that can be measured accurately using the instrument. For example, Take a spring balance whose range is 0-25. In this scale you can see that 1kg is divided into10 equal parts. Therefore the least value it can measure is 100grams which can be found out by, Measurement-1kg No. of divisions-10 Least count-1/10=0.01kg=100g Hence 100grams is the least count of the instrument.

Zero error arises when the measuring instrument doesn't start from exactly zero. Due to this zero error is present in each reading of a measure. There are two types of zero error- Positive zero error and Negative zero error. Positive zero error: If the zero marking of the vernier scale
