Thickness of a pencil measured by a screw gauge
Asked by admin @ in Physics viewed by 311 People
Thickness of a pencil measured by using a screw gauge(least count.001 cm) comes out to be 0.802cm. The percentage error in the measurement is
Answered by admin @
Given that:
Thickness t=0.802cm
Least count=0.001 cm
now error in measuring t=(0.802+-0.001)
%age error=0.001/0.802×100%
=0.125%
