When is a vernier callipers said to be free from zero error?

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

The least count of a vernier callipers is 0.01 cm and its zero error is + 0.02 cm. While measuring the length of a rod, the main scale reading is 4.8 cm and sixth division on vernier scale is in line with a marking on the main scale. Calculate the length of the rod.

Consider the vernier calipers as shown, the instrument has no zero error. What is the length of the rod (in mm) shown, if "1 msd = 1 mm " ? Use "7 msd = 8 vsd."

The least count of a vernier callipers is :

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

Describe in steps, how would you use a vernier callipers to measure the length of a small rod ?

A soil is said to be fertile when

The least count of a vernier callipers is 0.01 cm. Then, the error in the measurement is

Least count of a vernier callipers is 0.01 cm When the two jaws of the instrument touch each other the 5th division of the vernier scale coincide with a main scale division and the zero of the vernier scale lies to the left of the zero of the main scale. Furthermore while measuring the diameter of a sphere, the zero markof the vernier scale lies between 2.4 cm and 2.5 cm and the 6th vernier division coincides with a main scale division. Calculate the diameter of the sphere.

Define least count of a vernier callipers. How do you determine it?
