Question

An ordinary Vernier has 10 VSD = 9 MSD. A specially designed Vernier has 10 VSD = 11 MSD, with 1 MSD = 1 mm. Using the zero-error and measurement figures shown, select the correct statement(s). Image

G1 Physics · Accepted Answer

For the special Vernier, 10 VSD = 11 MSD, so its vernier constant magnitude is 0.1 mm. Reading the zero-error and object positions from the two figures gives zero-error magnitude 0.7 mm and corrected length 1.22 cm. Correct answers: A,C.
