Transcribed Image Text:

A small spherical object with volume V = 20 cm' and mass density p= 850 kg/m² is held (completely) under water. Take for the density of water 1000 kg/m³ and for the gravitational acceleration 8=9.8 m/s² A. Draw a force diagram for the object B. Calculate the Buoyant force and the gravitational force on the object C. Calculate the initial acceleration when the object is released. Also indicate the direction of the acceleration.
