The cylindrical tube of a spray pump has a cross-section of \(8\) cm2 one end of which has \(40\) fine holes each of area \(10^{-8}\) m2. If the liquid flows inside the tube with a speed of \(0.15\) m min-1 the speed with which the liquid is ejected through the holes is:
1. \(50\) m/s
2. \(5\) m/s
3. \(0.05\) m/s
4. \(0.5\) m/s
