प्रश्न
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.
उत्तर
If we know the number of vernier scale divisions (V.S.D.) coinciding with the main scale and a number of main scale divisions (M.S.D.) on the left-hand side of zero of vernier scale then Length recorded = Main scale reading + L.C. × V.S.D.
