While measuring the diameter of a sphere with a vernier callipers M.S.R and V.S.D. are 35 mm and 5 respectively . If the vernier scale coinciding with 19 division of main scale what is the diameter of the sphere?

In a vernier calipers, if 1 M.S.D. = 0.1 cm and the least count is 0.1 mm, then 1 V.S.D = 0.9 mm

The least counf of a vernier calipers having 20 vernier divisions when 1 M.S.D. =0.1 cm is "______" cm.
