A) 8.0 cm
B) 10.5 cm
C) 12.0 cm
D) None of the above
Correct Answer: C
Solution :
To see the container half-filled from top, water should be filled up to height \[x\] so that bottom of the container should appear to be raised upto height (21?x). As shown in figure apparent depth \[h'=(21-x)\] Real depth \[h=x\] \[\therefore \]\[\mu =\frac{h}{h'}\Rightarrow \frac{4}{3}=\frac{x}{21-x}\Rightarrow x=12\]cmYou need to login to perform this action.
