A cylindrical container of length L is full to the brim with a liquid which has mass density rho. It is placed on a weight scale; the scale reading is w. A light ball which would float on the liquid if allowed to do so, of volume V and mass m is pushed gently down and held beneath the surface of the liquid with a rigid rod of negligible volume as shown on the left. If instead of being pushed down by a rod, the ball is held in place by a thin string attached to the bottom of the container as shown on the right. What is the tension T in the string?

A glass full of water is placed on a weighing scale, which reads 10 N. A coin with weight 1 N is gently released into the water. At first, the coin accelerates as it falls and about halfway down the glass, the coin reaches terminal velocity. Eventually, the coin rests on the bottom of the glass. Acceleration due to gravity is 10 m divided by s to the power of 2 end exponent. The scale reads
