A vernier callipers having 1 main scale ...

A vernier callipers having `1` main scale division `= 0.1 cm` to have a least count of `0.02 cm`.If `n` be the number of divisions on vernier scale and `m` be the length of vernier scale, then.

A

n = 10,m = 0.5 cm

B

n =9,m = 0.4 cm

C

n = 10,m = 0.8 cm

D

n = 10,m = 0.2 cm

Text Solution

Verified by Experts

The correct Answer is:
C
`becauseL.C=1MSD-1VSD`
`:. 0.02=0.1-(m)/(n)rArr (m)/(n)=0.08`

Given that 1 M.S.D. of a vernier scale is 1 mm and its least count is 0.025 mm, then the number of divisions in the vernier scale is 25.

A vernier scale has 10 divisions . It slides over a main scale whose pitch is 1.0 mm . If the number of division on the main scale , to the left- hand side of zero of the vernier scale is 4 and the 8th vernier scale division coincides with the main scale find the measurement.

The diameter of a spherical bob is measured using a vernier callipers . 9 divisions of the main scale ,in the vernier callipers ,are equal to 10 divisions of vernier scale .One main scale division is 1 mm . The main scale reading is 10mm and 8th division of vernier scale was found to coincide exactly with one of the main scale division .If the given vernier callipers has positive zero error of 0.04 cm , then the radius of the bob is __________ xx10^(-2) cm.

A vernier scale has 10 divisions. It slides over the main scale, whose 1 M.S.D. is 1.0 mm. If the number of division to the left side of the zero of the vernier scale on the main scale is 49 and the 8th vernier scale division coincides with the main scale, calculate teh length in centimetres.
