The inner conductor of two coaxial cylindrical conductors carries a charge per unit length +λ C/m, and the outer conductor is grounded.
Given that the electric field between the two conductors is E = (λ/2πεor) rˆ, find an expression for the electric potential difference between the cylinders.

Water is siphoned from a large tank and discharges into the atmosphere through a 50-mm diameter tube. the end of the tube is b = 2.1 m below the tank bottom which is a = 7.4 m deep, and viscous effects are negligible. determine the maximum height h over which the water can be siphoned without cavitation occurring. atmospheric pressure is 101.4 kpa, and the water vapor pressure is 1.79 kpa (absolute)
