The main scale of vernier callipers has 10 equal divisions in 1 cm and 10 vernier scale divisions coincide with 9 main scale divisions, when both the jaws are in contact. Now, the above instrument is used to measure the external diameter of a cylinder. The 43rd division on the main scale is observed to the left of the zero of the vernier, when the object is held tightly in between the two jaws and the seventh division of the vernier coinsides with a division on the main scale, then

The diameter of a cylinder is measured using a vernier callipers with no zero error. It is found that zero of the vernier lies in between 5.10 cm and 5.15 cm of the main scale. The vernier has 50 divisions equivalent to 2.45 cm. The 24th division of the main scale exactly coincides with one of the main scale divisions. the diameter of the cylinder is

In an experiment, the angle are required to be measured using an instrument. 29 divisions of the main scale coincide with 30 divisions of the vernier scale. If the smallest division on the main scale is half a degree (0.5^(0)) , then the least count of the instument is
