In a given slide callipers 10 division of its vernier coincides with its 9 main scale divisions. If one main scale division is equal to 0.5 mm then find its least count.

The vernier scale of a travelling microscope has 50 divisions which coincide with 49 main scale divisions. If each main scale division is 0.5 mm, then the least count of the microscope is

The vernier scale of a travelling microscope has 50 divisions which coincide with 49 main scale divisions. If each main scale division is 0.5 mm, then the least count of the microscope is

In a vernier callipers 15 vernier scale divisions correspond to 14 main scale divisions and one main scale division is equal to 1.5 mm. An object is held scale division is equal to 1.5 mm. An object is held between the external jaw of the given vernier caliipers. If the zeroth division of the vernier scale is to the left of the 20^(th) divison of the main scale, find teh measurement of the object, if teh 14th division of the vernier scale coincides with the main scale division.

The least count of vernier callipers is 0.1 mm . The main scale reading before the zero of the vernier scale is 10 and the zeroth division of the vernier scale coincides with the main scale division. Given that each main scale division is 1mm . The measured value should be expressed as

The nth division of main " scale coincides with (n+1)th division of Vernier scale.Given one main scale division is equal to 'a' units.Then least count of Vernier is

A vernier callipers has 20 divisions on the vernier scale which coincides with 19mm on the main scale. Its least count is

The nth division of main scale coincides with (n +1) th division of vernier scale. Given one main division is equal to 'a' units. Find the least count of the vernier.

If 25venier scale divisions coincide with 20 main scale divisions. Find least count of venier calliper. ( One main scale division = 1mm )
