A vernier calliper has 20 divisions on the vernier scale. One centimetre on the main scale is divided into 20 equal parts. Find the least count of this instrument.

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

19 divisions on the main scale of a vernier callipers 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.

A vernier callipers has 20 divisions on the vernier scale which coincide with 19 divisions on the main scale. The least count of the instrument is 0.1 mm. The main scale divisions are of

N divisions on the main scale of a vernier calliper coincide with (N + 1) divisions of the vernier scale.If each division ofmain scale is 'a’ units, then the least count of the instrument is

In a vernier calliper, N divisions of vernier scale coincide with (N-1) divisions of main scale (in which division represent 1mm). The least count of the instrument in cm. should be

In a vernier callipers, N divisions of vernier scale coincide with (N-1) divisions of main scale (in which 1 division represents 1 mm). The least count of the instrument in cm should be

(M - 1) divisions on the main scale of a vernier calipers coincide with M divisions on the vernier scale. If each division on the main scale is of b unit, then least count of instrument is b M +1 b O M b M-1 1 O M

In a Vernier calipers, N divisions of Vernier scale coincides with (N-1 divisions of main scale (in which one division represent 2mm ).The least count of the instrument (in cm )

in an experiment the angles are required to be using an instrument, 29 divisions of the main scale exactly coincide with the 30 divisions of the vernier scale. If the sallest division of the main scale is half- a degree (= 0.5^(@) , then the least count of the instrument is :
