Question

A vessel with water is placed on a weighing pan and it reads 600 g. Now u ball of mass 40 g and density 0.80 g cm-3 is sunk into the water with a pin of negligible volume, as shown in figure keeping it sunk. The weighting pan will show a reading (A) 600 g (B) 550g (C) 650 g (D) 632 g

Tardigrade Admin · Accepted Answer

Volume of ball =(40/0.8)=50 cm 3 Downthrust on water =50 g. Therefore reading is 650 g.

Q. A vessel with water is placed on a weighing pan and it reads $600 g$ . Now u ball of mass $40 g$ and density $0.80 g c m^{- 3}$ is sunk into the water with a pin of negligible volume, as shown in figure keeping it sunk. The weighting pan will show a reading

600 g

550g

650 g

632 g

Volume of ball $= \frac{40}{0.8} = 50 c m^{3}$
Downthrust on water $= 50 g$ .
Therefore reading is $650 g$ .
