Explanation:

Given, Pitch scale reading (PSR) = 1 mm

Head scale coincidence (HSC) = 68

Least count (LC) = 0.01 mm

Assuming no zero error, we get

Corrected Head scale coincidence (CHSC) = 68

Thickness of the coin = PSR + (CHSC × LC)

= 1 + (68 × 0.01) mm

= 1.68 mm

Hence, Thickness of the coin is 1.68 mm.

Hope it helps you
