A student finds that the screw gauge that he is using to measure the thickness of a metal sheet has 50 divisions on the circular scale. If the pitch of the screw gauge is 0.05 cm, what is its least count?
A student got an experiment to find the volume of a glass slab of fixed thickness using a screw gauge. The dimension of the base was found to be 2 cm × 5 cm. The screw gauge reading for the thickness is shown below. Find the volume of the glass slab. Given the least count of the screw gauge is 0.01 mm.
In the laboratory, a student measures the thickness of a metal sheet using a screw gauge as shown in the given figure. What is the thickness of the sheet?
