Question

if ina varnier callipers 10vsd

Answer 1

Answer:

Explanation:

∵ 10th V.S.D concides with 8th M.S.D

so, 1 V.S.D = 8/10 M.S.D = 0.8 M.S.D

Also we know, 1 M.S.D = 1 mm

Now, least count = 1 M.S.D - 1 V.S.D

= 1 M.S.D - 0.8 M.S.D

= 0.2 M.S.D

= 0.2 × 1 mm [∵ 1M.S.D = 1mm ]

= 0.2 mm

Hence, least count = 0.2 mm
