A cylindrical container of length L is full of a liquid which has mass density ρ. It is placed on a weigh-scale; the scale reading is W. A ball which would float on the liquid if allowed to do so, of volume V and mass m is pushed gently down and held beneath the surface of the liquid with a rigid rod of negligible volume as shown.
What is the reading of the scale when the ball is fully immersed?
D) None of these
since the ball can float on liquid, force of buoyancy acts equally all the areas so the weight remains unchanged.
is it the right answer ?
