Question

while measuring the length of pencil with vernier callipers, the main scale reading is 4.6 cm and 6th division of vernier scale coincides with main scale division.find the length of pencil if least count is 0.01 CM and zero error is +0.04 CM ​

Answer 1

Answer:

Length of the rod = observed reading - zero  error

=MSR+(V.C×L.C)−zeroerror

=4.6+(6×0.01)−[−0.03]

=(4.6+0.06)+(0.03)

=4.66+0.03

=4.69cm

Explanation:

hope thso will help u

Answer 2

Answer:

Length of the rod = observed reading - zero  error

=MSR+(V.C×L.C)−zeroerror

=4.6+(6×0.01)−[−0.03]

=(4.6+0.06)+(0.03)

=4.66+0.03

=4.69cm
