Why all voltage level are multiples of 11, like 220V, 440V,
1100V instead of 200V, 400V, 1000V?

The system shown in the figure is in equilibrium. The metal spheres are identical and each has a mass of 2 kg. The surface areas of the pistons are equal and 100 square centimeters each. The density of water is 1 g per cubic centimeter. Assuming that the frictions and masses of the pistons are negligible, what is the mass of G? ( g = 10N/kg )
