प्रश्न
Consider the following case where the zero of vernier scale and the zero of the main scale are clearly seen. If L.C. of the vernier calipers is 0.01 cm, write the zero error and zero correction of the following.
उत्तर
Here, zero of the vernier scale coincides with the zero of the main scale, So, the zero error and zero error correction is nil.
