A vernier calipers has 25 divisions on the vernier scale, An object is held between the external jaw of this instrument. If the zeroth division of the vernier scale is to the left 32nd division of the main scale and the 20th division of the vernier scale coincides with a main scale division, determine the measurement of the object.` (Take 1 M.S.D. = 0.5 mm )`

Text Solution

Verified by Experts

Length or diameter = [ difference of the observed reading on the two jaws with the object held] -[difference of the observed reading when the jaws are closed].
(ii) M.S.R = 10.2 cm
V.C.D. = 6

A vernier calipers has 25 divisions on the vernier scale. An object is held between the external jaws of this instrument. If the zeroeth division of the vernier scale is to the left of the 32nd division of the main scale and the 20th division of the vernier scale coincides with a main scale division, determine the measurement of the object. (Take 1 M.S.D. = 0.5 mm).

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 between the external jaws of the given vernier callipers. If the zeroth division of the vernier scale is to the left of the 20th division of the main scale, find the measurement of the object, if the 14th division of the vernier scale coincides with the main scale division.
