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 reading of the scale when the ball is fully immersed
(a). `w-rhoVg`
(b). w
(c). `w+mg-rhoVg`
(d). none of these

Text Solution

Verified by Experts

The correct Answer is:
C
Weight mg is entered while weight `rhoVg` of liquid is overflowed.
