A vernier calipers has 1mm marks on the main scale. It has 20 equal divisions on the Verier scale which match with 16 main scale divisions. For this Vernier calipers, the least count is

In a vernier callipers n divisions of its main scale match with (n+5) divisions on its vernier scale. Each division of the main scale is of x unit. Using the vernier principle, find the least count.

In a vernier calipers, 1 cm of the main scale is divided into 20 equal parts. 19 divisions of the main scale coincide with 20 divisions on the vernier scale . Find the least count of the instrument.

In a vernier callipers, n divisions of its main scale match with (n+1) divisions on its vernier scale. Each division of the main scale is a units. Using the vernier principle, calculate its least count.

Least count of a vernier callipers is 0.01 cm When the two jaws of the instrument touch each other the 5th division of the vernier scale coincide with a main scale division and the zero of the vernier scale lies to the left of the zero of the main scale. Furthermore while measuring the diameter of a sphere, the zero markof the vernier scale lies between 2.4 cm and 2.5 cm and the 6th vernier division coincides with a main scale division. Calculate the diameter of the sphere.

The diameter of a cylinder is measured using a vernier callipers with no zero error . It is found that the zero of the vernier scale lies between 5.10 and 5.15 cm of the main scale . The 24 th division of the vernier scale exactly coincides with one of the main scale divisions . The diameter of the cylinder is

Read the special type off vernier 20 division of vernier scale are matching with 19 divisions of main scale

In a vernier callipers, one main scale division is x cm and n divisions of the vernier scale coincide with (n-1) divisions of the main scale. The least count (in cm) of the callipers is :-

19 divisions on the main scale of a vernier calipers coincide with 20 divisions on the vernier scale. If each division on the main scale is of 1 cm , determine the least count of instrument.

The edge of a cube is measured using a vernier callipers. [ 9 divisions of the main scale is equal to 10 divisions of the vernier scale and 1 main scale dividsion is 1 mm ]. The main scale division reading is 10 and 1st division of vernier scale was found to be coinciding with the main scale. The mass of the cube is 2.736 g . Calculate the density in g//cm^3 upto correct significant figures.
