Question

The observed reading of the thickness of a glass plate measured with a screw gauge is $2.33$ mm. The zero error is $-0.03$ mm (negative). What is the correct thickness of the plate?

Answer 1

Given data:

• The measurement of the glass plate = $2.33$ mm
• The error is $-0.03$ mm

Finding the correct thickness:

1. The correct thickness of the plate is = ( observe thickness - zero error) = $2.33-(-0.03)=2.36mm$
2. Hence, the correct thickness is $2.36$ mm.
