Explanation:

Step1: Read main scale reading (MSR)

The vernier scale's zero mark is between 0.6 cm and 0.7 cm on the main scale, so MSR = 0.6 cm.

Step2: Find vernier coincidence (VC)

The 7th division of the vernier scale aligns with a main scale division, so VC = 7.

Step3: Calculate vernier scale contribution

Vernier contribution = VC × Least Count = $7 \times 0.01 = 0.07$ cm

Step4: Compute total measurement

Total reading = MSR + Vernier contribution = $0.6 + 0.07$

Answer:

0.67 cm
