Yоu аre building а tоy mоbile, copying the design shown аbove (see also description below). The numbers in the figure indicate the relative lengths of the rods on each side of their supporting cords. Object A has a mass of 1.0 kg. What should be the mass of object B? Assume the cords are massless. Description: 2 horizontal bars & 3 masses hang from ceiling by a cord.Mass A is 2 units to left of cord on top bar. 2nd bar hangs 1 unit to right of cord.Mass B hangs 1 unit to right of cord on lower bar. Unknown mass hangs 2 units to left of cord.
