उत्तर
The presentation of the data in a tabular form helps in quickly grasping and analyzing the recorded observations. For example, to measure a diameter using a vernier caliper we record the following data in a tabular form as follows
Vernier caliper
| No. of observations | Main scale reading (cm) | No. of vernier divisions p coinciding with main scale | Vernier reading =L.C. X p (cm) | Observed diameter |
| 1 | ||||
| 2 | ||||
| 3 |
The measurements corresponding to one physical quantity from one instrument must be recorded in one table. And the name of the instrument should be written on top. Observation must be recorded up to the limit of the instrument and form the recorded individual observations, calculate the mean value, and record it at the bottom of the column.

When is a vernier Callipers said to be free from zero error?
Name the part of the vernier callipers which is used to measure the following
External diameter of a tube
(a) A vernier scale has 10 divisions. It slides over the main scale, whose pitch is 1.0 mm. If the number of divisions on the left hand of zero of the vernier scale on the main scale is 56 and the 8th vernier scale division coincides with the main scale, calculate the length in centimetres.
(b) If the above instrument has a negative error of 0.07 cm, calculate the corrected length.
State the formula for calculating length if:
The reading of the main scale is known and the number of vernier scale divisions coinciding with the main scale is known.
The level of water in a measuring cylinder is 12.5 ml. When a stone is lowered in it, the volume is 21.0 ml. Find the volume of the stone.
What is the backlash error?
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.
