Question

A venier calipers has two sliding jaws with scales marked as shown in the figure. When a brss rod of length 5.23 cm was held between the jaws, the zero of jaw A was found to lie between the 34th and 35th main scale division with the 3rd division on the vernier coinciding witha main scale division. Find the M.S.R. and V.C.D. for the venier scale on jaw B.

Answer 1

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
