The diameter of a cylinder is measured using a vernier calipers with no zero error. It is found that the zero of the vernier scale …
A vernier calipers has 1mm marks on the main scale. It has 20 equal divisions on the Vernier scale which match with 16 main scale divisions. Calculate the least count of Vernier calipers.
Vernier calipers are precision instruments used for measuring internal and external dimensions with high accuracy. The instrument consists of a main scale and a Vernier …
If the velocity of light c, the constant of gravitation G, and Plank’s constant h are chosen as fundamental units, find the dimensions of mass, length, and time in terms of c, G, and h.
In physics, the choice of fundamental units can vary depending on the field of study. In certain advanced fields, such as theoretical physics, it can …
If the nth division of main scale coincides with (n+1)th division of vernier scale, find the least count of the vernier. Given one main scale divisions equal to ‘a’ units
In the context of precision measurements, the vernier caliper is an instrument that allows for more precise measurements than a standard ruler or measuring tape. …
