A Ping-Pong ball with mass 1.5 g is attached by a thread to the bottom of a beaker. When the beaker is %uFB01lled with water so that the ball is totally submerged, the tension in the thread is 0.029 N. Determine the diameter of the ball. The density of water is 1000 kg/m3 and the acceleration of gravity is 9.81 m/s^2.
