A student took the least count of a vernier calliper as 0.01 mm instead of 0.01 cm and found that the length of a copper rod was 4.909 cm. If one M.S.D. = 1 mm, then find
(1) the main scale reading
(2) the vernier coinciding division
(3) the correct length of the rod

The least count of a vernier callipers is 0.01 cm. Then, the error in the measurement is

The vernier constant of a vernier callipers is 0.1 mm and it has a positive zero error of 0.04 cm . While measuring diameter of a rod, the main scale reading is 1.2 cm and 5th vernier division is coinciding with any scale division. The correct diameter of the rod is

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

The least count of a veriner callipers is (1)/(100)cm . The value of one division on the main scale is 1mm. The, the number of divisions on the main scale that coincide with N divisions of the vernier is

The least count of a veriner callipers is (1)/(100)cm . The value of one division on the main scale is 1mm. The, the number of divisions on the main scale that coincide with N divisions of the vernier is

While measuring the length of a copper rod using a vernier calliper, the zero of the vernier scale ws found to be between 4.6 cm and 4.7 cm on the main scale. The 6th division of the vernier scale is found to coincide with a division on the main scale. Find the length of the rod if the least count is 0.01 cm.
