A small stone of mass m ( = 200 g ) is held underwater in a tall jar and allowed to fall as shown in the following figure. The free-body diagram of the stone is also shown.
(i) What does F2 represent?
(ii) What does m1 represent?
(iii) What is the net force acting on the stone?
(iv) What is the acceleration of the stone as it falls through water? Neglect the force due to viscosity. Assume that volume of stone = 80 cml, density of water = 1.0 g cm-3 and acceleration due to gravity g = 10 ms-2.
