A vernier callipers has a least count of 1mm of its main scale. If 11 divisions of its main scale coincides with 12 divisions of vernier scale then its least count will be :-

If 50 Vernier divisions are equal to 49 main scal divisions of a travelling microscope and on smallest reading of main scale is 0.5 mm, th Vernier constant of travelling microscope is:

How to Read a Linear Vernier Scale

A student measured the length of a rod and wrote it as 3.50 cm. Which instrument did he use to measure it :A meter scaleA vernier calliper where the 10 divisions in vernier scale matches with 9 divisions in main scale and main scale has 10 divisions in 1 cmA screw gauge having 100 divisions in the circular scale and pitch is 1 mmA screw gauge having 50 divisions in the circular scale and pitch is 1 mm
