(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

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.

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

If N divisions on the vernier scale are equal to (N-2) divisions on the main scale then the least count Is "______"

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 :

In a experiment the angle are required to be measured using an instrument. 26 divisions of the main scale exactly coincide with the 30 divisions of the vernier scale . If the smallest division of the main scale is half -a-degree (=0.5^(@)) then the least count of the instrument is .

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

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.

The main scale of a vernier callipers has n divisions/cm. n divisions of the vernier scale coincide with (n-1) divisions of main scale. The least count of the vernier callipers is,

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