A) water levels in both sections A and B go up
B) water level in section A goes up and that in B comes down
C) water level in section A comes down and that in B it goes up
D) water levels remain the same in both sections
Correct Answer: A
Solution :
According to Bernoulli?s principle, \[\operatorname{P} + \frac{1}{2} \rho {{v}^{2}}= constant\] At the sides the velocity is higher, so the pressure is lower. But the pressure at a given horizontal level must be equal; therefore the liquid rises at the sides to some height to compensate for this drop in pressure.
