Look at the measurement of vernier calipers:

 

 

 

 

 

 

a. What is its main scale reading?
b. What is its coinciding division on the vernier scale? Calculate the total reading on the vernier calipers.

Ans:

a. The main scale reading (reading to which zero of vernier scale coincides) is 2.5 cm.
b. The coinciding division on vernier scale is 8th division.
c. The total reading: 2.5+8(0.01) cm = 2.5 + 0.08 cm = 2.58 cm
