Find the thickness of a five rupee coin ...

Find the thickness of a five rupee coin with the screw gauge. If the pitch scale reading is 1 mm and its head scale coincidence is 68 .

Text Solution

Verified by Experts

Given : pitch scale reading = 1 m m
Head scale coincidence = 68
The thickness of a fire rupee coin = PSR + HSC `xx` L.C `pm` ZE
` 1 m m + 68 xx 0 . 01 m m `
`= 1 m m + 0 . 68 m m `
= 1 . 68 m m
