Units and Measurements · Significant figures & errors
In a Vernier calipers, when both jaws touch each other, zero of the Vernier scale is shifted to the right of zero of the main scale and Vernier division coincides with a main scale reading. If the value of 1 main scale division is 1 mm and there are 10 Vernier scale divisions, then the Vernier caliper has
- (1)0.07 cm negative zero error
- (2)0.7 cm negative zero error
- (3)0.07 cm positive zero error
- (4)0.7 cm positive zero error
