A block of weight W is suspended from a spring balance. The lower surface of the block rests on a weighing machine. The spring balance reads W1 and the weighing machine reads W2. (W, W1, W2 are in the same unit):
(A) W = W1 + W2 if the system is at rest
(B) W > W1 + W2 if the system moves down with some acceleration
(C) W1 > W2 if the system moves up with some acceleration
(D) no relation between W1 and W2 can be obtained with the given description of the system
