The least count of three instruments are 1 mm, 0.1 mm and 0.01 mm. Which one has the greatest precision?

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

Express 0.01 mm in cms.

Name the instrument which has the least count 0.01 mm.

A thin 1m long rod has a radius of 5mm . A force of 50pi KN is applied at one end to determine its Young's modulus Assume that the force is exactly known. If the least count in the measurement of all lengths is 0.01mm which of the following statements is false ?

Name the instrument which has the least count 0.1 mm .

A vernier calliper has 20 divisions on the vernier scale, which coincide with 19 on the main scale. The least count of the instrument is 0.1 mm. The main scale divisions are of :
