Vernier Calipers
 1) What is vernier constant? least count angular vernier zero correction least constant

 2) What is the function of sliding strip or rod? to measure the diameter of certain objects to measure the radius of certain objects to measure the depth of certain objects to measure the width of certain objects

 3) Why is a slide callipers called a 'Vernier Callipers'? Its idea was first conceived at Vernier in southern Germany. It is the Latin name for 'slide callipers' None of the above It was first designed by a French mathematician, Pierre Vernier.

 4) Which of the following measurements cannot be made by a vernier calliper? Measuring the internal diameter of a cylindrical object or the depth of a vessel. Measuring the height of a tower. Measuring the outer diameter of a spherical or cylindrical object. Measuring the length of an iron nail.

 5) Which of the following is a true statement? Zero error is a algebraically subtracted from the observed reading. All of the above. Zero correction is algebraically added to the observed reading Negative of zero error is zero correction.

 6) Which of the following is incorrect with regard to zero error? It is the error in the vernier callipers. It arises due to wear and tear of the instrument. It occurs if the zeros of main scale and vernier scale do not coincide. It is positive when vernier zero is to the left of main scale and negative if it is to the right.

 7) Least count: metre scale - 1mm, vernier callipers - 0.1mm, screw guage and spherometer - 0.01mm. Which has the least accuracy? Metre scale Spherometer Vernier callipers Screw guage

 8) Vernier Constant is given by: V.C.= 1 V.S.D.-1 V.S.D V.C.= 1 M.S.D.-1 V.S.D V.C.= 1 M.S.D./1 V.S.D V.C.= 1 M.S.D.+1 V.S.D

 9) Principle of vernier callipers: N main scale division = N vernier scale divisions. N main scale division = (N-1) vernier scale divisions. N vernier scale division = (N/2) main scale divisions. N vernier scale division = (N-1) main scale divisions.

 10) A student used a vernier caliper to measure the length of his pencil.He found that the main scale showed a reading of 8.3 and vernier scale coincides with 5th position to the main scale.What was the correct measurement of the length of the pencil? 8.5 8.8 8.3 8.35

 11) The diagram below shows the part of a vernier caliper used to measure the diameter of a soft drink can.What is the reading shown? 6.47 6.34 6.37 6.44

 12) During the measurement of the inner diameter of a measuring jar, Arun got the reading as follows . What is the reading shown? 3.5 cm 3.54 cm 3.34 cm 3.03 cm
