Question

1. To measure the volume of the material of a given hollow cylinder, using Vernier calipers.
1. A Vernier Callipers is necessary and suitable only for certain types of measurement where the
required dimension of the object is freely accessible. It cannot be used in many situations. e.g. suppose a hole of
diameter 'd' is to be drilled into a metal block. If the diameter d is small - say 2 mm, neither the diameter nor the
depth of the hole can be measured with a Vernier Callipers.
2. It is also important to realise that use of Vernier Callipers for measuring length/width/thickness etc. is
essential only when the desired degree of precision in the result (say determination of the volume of a wire) is
high. It is meaningless to use it where precision in measurement is not going to affect the result much. For
example, in a simple pendulum experiment, to measure the diameter of the bob, since L >> d.
3. What is Vernier constant?
4. What is meant by instrumental error in Vernier Callipers?
