JEE Main 2024 — Experimental Physics Question with Solution
JEE Main 2024 (08 Apr Shift 2)
Question
There are 100 divisions on the circular scale of a screw gauge of pitch . With no measuring quantity in between the jaws, the zero of the circular scale lies 5 divisions below the reference line. The diameter of a wire is then measured using this screw gauge. It is found that 4 linear scale divisions are clearly visible while 60 divisions on circular scale coincide with the reference line. The diameter of the wire is :
