The least count of a vernier calipers is 0.01 cm and its zero error is + 0.02 cm. While measuring the length of rod, the main scale reading is 4.8 cm and sixth division on vernier scale is in line with a marking on main scale. calculate the length of rod.

Hey there!
Given,
L.C = 0.01 cm
Zero error = + 0.02 cm
Main scale reading = 4.8 cm
number of vernier division coinciding with the main scale division is 6.
Length of rod = observed reading - zero error
=[ main scale reading + coinciding vernier division] - zero error
= 4.8 + 0.06 cm - (+0.02)
= 4.86 - 0.02 = 4.84 cm
Hope It Helps You!

Answer:
4.84 cm
Explanation:
Given that,
Least count = 0.01 cm
Zero error = +0.02 cm
Main Scale Reading(M.S.R) = 4.8 cm
Vernier Scale Divisions(V.S.D) = 6 (sixth division)
So, Vernier Scale Reading = 6 × Least Count
= 6 × 0.01 cm
= 0.06 cm
Length of the rod = M.S.R+V.S.D-zero error
= 4.8 + 0.06 - 0.02
= 4.86 - 0.02
= 4.84 cm
