answer is for one0.01 cm and for two +0.03​

Answer 1

Hey there!

Given,

Value of 1 division on main scale = 1 mm

No. of divisions on the vernier scale = 10 divisions

i) L.C = Value of one main scale division / Total no.of divisions on vernier scale

         = 1/10

          = 0.1 mm = 0.01 cm

ii) Positive zero error = 3 * L.C

                                   = 3 * 0.01 cm

                                   = + 0.03 cm

                                   = + 0.3 mm
