#### A conical flask of mass 10 kg and base area as 10^{3} cm^{2} is floating in liquid of relative density 1.2, as shown in the figure. The force that liquid exerts on curved surface of conical flask will be (Given g = 10 m/s^{2})

- 20 N downward direction
- 40 N in downward direction
- can be determined only if q is given
- 20 N in upward direction

#### The correct answer is: 20 N downward direction
