A cylindrical 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 ball of volume `V` and mass `m` which wold float on the liquid, if allowed to do so, is pushed gently downand held beneath the surface of the liquid with a rigid rod of negligible volume as shwon on the left.
What is the reading on the scale?

A

(a)`W-rhoVg`

B

(b)`W`

C

(c) `W+mg-rhoVg`

D

(d) none

Text Solution

Verified by Experts

The correct Answer is:
C
Reading of scale:
`W'=` weight of ball `+` weight of the remaint liquid
`=mg=W-Mg`
`=W+mg-Vrhog`

A container open from top, filled with water (density rho_w ) upto the top, is placed on a weighing machine and the reading is W. A wooden ball of volume V and mass m is put in the water by the given two arrangements. In arrangement–1, the ball is connected by a rigid rod (of negligible volume) and pushed in the water. In arrange- ment–2, the ball is attached with bottom by a massless string. The reading of weighing machine, (density of wood is less than water) (choose incorrect option)
