QNEET-2021-Ph-628: NEET 2021 Physics - Class 11 NEET-2021-Ph-628 Solution: A screw gauge gives the following readings when used to measure …
A screw gauge gives the following readings when used to measure the diameter of a wire Main scale reading: 0 mm Circular scale reading: 52 divisions Given that 1 mm on main scale corresponds to 100 divisions on the circular scale. The diameter of the wire from the above data is: 0.052 cm 0.52 cm 0.026 cm 0.26 cm
Multiple Choice Options
- A 0.052 cm
- B 0.52 cm
- C 0.026 cm
- D 0.26 cm
Step-by-Step Verified Solution
L.C. = P i t c h C S D
= 1 m m 100 = 0.01 m = 0.001 cm
Radius = M.S. + CSR(L.C)
= 0 + 52 (0.001)
= 0.052 cm
