alleryWith jaws closed, the 4th vernier mark lines up on the positive side. Least count is 0.01 cm. The zero error is:
A+0.004 cm
B+0.4 cm
C+0.04 cm
D-0.04 cm
Answer & Solution
Correct answer: C. +0.04 cm
Zero error is n times the least count, so 4 times 0.01 cm on the positive side gives +0.04 cm.
