A large air-filled rubber ball is tethered to the bottom of a swimming pool. The tension in the tether is 100N. The mass of the rubber in the ball itself is 2kg while pwater=1000kgm(-3) and pair=1.2 kgm(-3). What is the volume of the ball?

  • physics - ,

    tension-weight=bouyancy

    tension-2*g - pair*volume=pwater*volume

    solve this for volume.
