Medium$A$ gardening pipe having an internal radius '$R$' is connected to a water sprinkler having '$n$' holes each of radius '$r$'. The water in the pipe has a speed '$v$'. The speed of water leaving the sprinkler is
- A$\left(\frac{R^2}{n r^2}\right) v$
- B$\frac{R^2 v}{n r^2}$
- C$\left(\frac{n r^2}{R^2}\right) v$
- D$\left(\frac{n R^2}{r^2}\right) v$
