Two metal blocks A and B were placed on ...

Two metal blocks A and B were placed on the two pans ofa common balance and the beam of the balancec was horizontal. However, when the blocks were interchanged and block B was placed in the left pan and block A in the right pan, the beam was not balanced and tilted down toward the left. Discuss teh various factors that could be the cause of this. Are teh masses of two blocks equl?
