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 lies on the right of the main scale.

Also, the 5th vernier division is coinciding with some main scale division
Thus, zero error = 0 + 5 x L.C. = -0.05 cm
Hence zero correction = 0.05 cm

Name the instrument which can accurately measure the following

The internal diameter of the neck of a water bottle


In a vernier callipers, 19 main scale divisions coincide with 20 vernier scale divisions. If the main scale has 20 divisions in a centimetre, calculate

  1. pitch
  2. L.C. of vernier callipers.

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

  1. pitch
  2. observed diameter.
  3. least count
  4. corrected diameter.

State the formula for calculating the pitch of screw.


The Wavelength of a particular colour is 5400Å. Express it in nanometer and metre.


In the following figure, the pitch of the screw is 1 mm. Calculate:
(i) the least count of screw gauge and
(ii) the reading represented in the figure.


What is the least count in the case of the following instrument?

Metre scale


If the 47th division of the circular scale coincides with the zero of the main scale of a screw gauge of least count 0.01 mm and having 50 circular divisions, what is it's zero error?

What is meant by zero error of a vernier caliper? How is it determined? Draw neat diagrams to explain it. How is it taken into account to get the correct measurement?
