range 0-250 gwt, least count 2.5 gmt.
Radius = 2 cm = 0.02 m
Volume of sphere = 4πR3/3 = 4π(0.02)3/3 = 33.5 x 10-6 m3
Mass of sphere = ρV = 7x103x33.5x10-6 = 234.5 gm = 234.5 gwt.
So it's within the range of 0-250 gwt, spring balance, and it has the same least count as 0-500 gwt. But it'll be easier to read on 0-250 gwt.
