📘Question

The tube of length L is shown in the figure. The radius of cross section at the point (1) is 2 cm and at the point (2) is 1 cm, respectively. If the velocity of water entering at point (1) is 2 m/s, then velocity of water leaving the point (2) will be : 

(1) 2 m/s 

(2) 4 m/s 

(3) 6 m/s 

(4) 8 m/s                                  (JEE-2025)   

✅ Answer

The tube of length L is shown in the figure. The radius of cross section at the point (1) is 2 cm and at the point (2) is 1 cm, respectively. If the velocity of water entering at point (1) is 2 m/s, then velocity of water leaving the point (2) will be :  (1) 2 m/s  (2) 4 m/s  (3) 6 m/s  (4) 8 m/s
