T1. The problem statement, all variables and given/known data a wooden ball of mass m is kept inside water by the help of a massless string shown in the figure. One end of the string is fixed at the bottom of the vessel. when the vessel containing the water is accelerated upwards with acceleration a , will the tension increase and why? 2. Relevant equations B = Vdg, Vdg-mg-T = ma 3. The attempt at a solution The answer is that the tension increases, but according to the equations above, buoyancy remains constant and the new tension is T = Vdg-mg-ma, which is lesser than before(Vdg-mg).
