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.

The final result of the calculation in an experiment is 125,347,200. Express the number in term of significant place when accuracy is between 1 and 1000
When does a vernier callipers has the negative error?
State the correction if the positive error is 7 divisions when the least count is 0.01 cm.
Which part of vernier callipers is used to measure the internal diameter of a hollow cylinder?
A micrometre screw gauge has a negative zero error of 8 divisions. While measuring the diameter of a wire the reading on the main scale is 3 divisions and the 24th circular scale division coincides with baseline.
If the number of divisions on the main scale are 20 to a centimetre and circular scale has 50 divisions, calculate
- pitch
- observed diameter.
- least count
- corrected diameter.
State the formula for calculating the pitch of screw.
