A cylinderical container of length L is ...


A cylinderical container of length L is full to the brim with a liquid which has mass density `rho`. It is placed on a weight scale, the scale reading is w. A light wall 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 on the left
Q. What is the mass M of liquid which overflowed while the ball was being pushed into the liquid?
(a). `rhoV`
(b). `m`
(c). `m-rhoV`
(d). none of these

Text Solution

Verified by Experts
