1. 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.
Solution:
From the data given,
Pitch scale reading (\(PSR\)) \(=\) 1 \(cm\)
Head scale coincidence (\(HSC\)) \(=\) 68
Let us consider,
Least count (\(LC\)) \(=\) \(mm\)
The formula to calculate the thickness of the coin,
Answer variants:
\(\pm\)
\(-\)
\(\times\)
LC
ZE
HSC
PSR
\(+\)
Substitute the values in the formula,
Thickness of the ball : \(mm\)
