Question

35. While measuring the length of a copper rod using a vernier calliper, the zero of the vernier scale was
found to be between 4.6 cm and 4.7 cm on the main scale. The oth division of the vernier scale is found
to coincide with a division on the main scale. Find the length of the rod if the least count is 0.01 cm.​

Answer 1

Answer:

M.S.R = 4.6 cm = 4.6 mm

V.C.D = 6

L.C = 0.01 cm = 0.1

I = M.S.R + (V.C.D×L.C)=

46 + 6 xx 0.1 = 46.6mm = 4.66` cm.
