Expert Answer:

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.
