प्रश्न
We can find the diameter of a wire by wrapping it around a pencil and measuring the length of turns with the help of a meter scale. Is this approach more accurate than determining the diameter of the wire with the help of a screw gauge?

उत्तर
No, we cannot measure the diameter of a wire by wrapping it around a pencil because it is not very accurate. We can use a screw gauge for this purpose as it can measure the diameter correct up to 1/100 of a millimeter or even less.
