A vessel with water is placed on a weighing pan and reads 600 g. Now a ball of 40 g and density 0.80 g/cc is sunk into the water with a pin as shown in fig. keeping it sunk. The weighing pan will show a reading
Text Solution
Verified by ExpertsThe correct answer is:
C
Upthrust on ball = weight of displaced water
Dyne or 50 gm
As the ball is sunk into the water with a pin by applying
downward force equal to upthrust on it.
So reading of weighing pan = weight of water + downward
force against upthrust
= 600 + 50 = 650 gm.
