The diameter of the steel ball is measured using a vernier caliper which has divisions of 0.1 cm on its main scale nad 10 division of its vernier scale match 9 division on the main scale. Three such measurements for a ball are as follows. If the zero error is 0.03cm, then mean corrected diameter is ............. cm.

1.	The diameter of the steel ball is measured using a vernier caliper which has divisions of 0.1 cm on its main scale nad 10 division of its vernier scale match 9 division on the main scale. Three such measurements for a ball are as follows. If the zero error is 0.03cm, then mean corrected diameter is ............. cm.
Answer» 0.56 0.53 0.59 0.52 Solution :LEAST COUNT = 0.01 CM `ZE=-0.03cm` `"Mean "=(0.61+0.57+0.59)/(3)` `=1.77` `therefore"Mean CORRECTED diameter"=0.59cm`
