Question
A large tank is filled with water (density = 103 kg/m3). A small hole is made at a depth 10 m below water surface. The range of water issuing out of the hole is Ron ground. What extra pressure must be applied on the water surface so that the range becomes 2R (take 1 atm = 105 Pa and g = 10 m/s2):
- 9 atm
- 4 atm
- 5 atm
- 3 atm
The correct answer is: 3 atm
