The radius of the sphere is measured using a meter
The radius of the sphere is measured using a
meter screw gauge having a pitch 0.5 mm
and 50 divisions on it. If the main scale
reading is 2.5 mm and the circular scale
reading is 20 divisions then calculate the
minimum percentage error in it
a) 0.9 % b) 0.4 %
c) 1.1 % d) 4.2 %
