Asolid block of mass m is suspended in a liquid by a thread. the density of the block is greater than that of the liquid. initially, the fluid level is such that the block is at a depth d and the tension in the thread is t. then, the fluid level is decreased such that the depth is 0.5d. what is the tension in the thread when the block is at the new depth?
