The Formula to find Least count of vernier caliper is

• L.C. = (Largest division on Main Scale ) / (Total number of divisions on Vernier Scale)
• L.C. = (Smallest division on Main Scale ) / (Total number of divisions on Vernier Scale)
• L.C. = (Total number of divisions on Vernier Scale) / (Smallest division on Main Scale)
• L.C. = (Smallest division on Main Scale + Largest division on Main scale ) / (Total number of divisions on Vernier Scale)

What is the least count (L.C.) of the Vernier caliper if the smallest division on the main scale is 0.1cm and total division on the vernier scale is 10div ?

• 0.001cm

• 0.0001cm

• 0.01cm

• 0.1cm

The least count of a vernier is 0.001 cm. What is the order upto which it can measure length accurately?

• 1000mm
• 0.001cm
• 0.1cm
• 0.01cm

When Zero Error is positive in Vernier Caliper?

• The Zero Error is positive when the zero of vernier scale is to the left of the zero of main scale
• The Zero Error is positive when the zero of vernier scale is to the right of the zero of main scale
• The Zero Error is positive when the zero of main scale is in the middle of vernier scale.
• The Zero Error is positive when the zero of main scale is to the left of the first division of vernier scale

Vernier caliper helps in measuring

• external diameter
• internal diameter
• thickness and depth of narrow tubes
• all of them

What is meant by least count of an instrument?

• It is the smallest measurement that can be made with the given instrument
• It is the largest measurement that can be made on an instrument
• It is the smallest measurement that can be made on vernier scale
• It is the smallest measurement that can be madeon ruler

What part of the vernier calipers is the vernier scale?

• The fixed scale along the main scale is called vernier scale
• The main scale is called vernier scale
• The sliding scale along the main scale is called vernier scale
• None

What is the function of sliding strip or rod?

• to measure the diameter of certain objects
• to measure the depth of certain objects
• to measure the radius of certain objects
• to measure the width of certain objects

Which of the following measurements cannot be made by a vernier calliper?

• Measuring the height of a tower.
• Measuring the internal diameter of a cylindrical object or the depth of a vessel.
• Measuring the outer diameter of a spherical or cylindrical object
• Measuring the length of an iron nail.

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
