A ping pong ball can be approximated as an air-filled sphere of radius 0.039 m and an average density of 840 kg/m3. The pin-pong ball is held fully submerged in water in a large tank such that it is just under the surface. Calculate the value of the downward force that is required to keep the ball submerged. [Density of water = 1.00 x 103 kg/m3]

A small plastic ball (similar to a ping-pong ball) with mass 6 g is attached by a thread to the bottom of a beaker. When the beaker is filled with water so that the ball is totally sub- merged, the tension in the thread is 0.028 N. The density of water is 1000 kg/mº and the acceleration of gravity is 9.81 m/s. 68 Determine the diameter of the ball. Answer in units of cm.
