Introduction Of Vernier Callipers

The diameter of a spherical bob is measured using a vernier callipers . 9 divisions of the main scale ,in the vernier callipers ,are equal to 10 divisions of vernier scale .One main scale division is 1 mm . The main scale reading is 10mm and 8th division of vernier scale was found to coincide exactly with one of the main scale division .If the given vernier callipers has positive zero error of 0.04 cm , then the radius of the bob is __________ xx10^(-2) cm.

The main scale of a vernier calliper reads in mm and its vernier scale is divided into 8 divisions, which coincides with 7 divisions of the main scale. It was also observed that, when the two jaws are brought in contact, the zero of the vernier scale coincided with the zero of the main scale. The edge length of a cube is measured using this vernier calliper. The main scale reads 12 mm and 2^("nd") division of the vernier scale coincides with the main scale. The edge length (in mm) of the cube is

Describe an experiment to find the volume of a sphere using vernier callipers.

The zero error in a Vernier callipers is said to be positive when

Using upper pair of jaws of Vernier Callipers, we can measure
