2. suppose a dipole ⃗p is placed in a nonuniform electric field e⃗ = eˆi that points along the x axis. if e⃗ depends only on x and the electric field varies very slowly from the negative to the positive charge in the dipole (2l is the distance between charges in the dipole), show that the net force on the dipole is f⃗ = (⃗p · de⃗ dx )ˆi.

Consider a one meter long horizontal pipe with a constant 100 cm^2 cross sectional area. water flows rightward into the pipe at x = 0 with flow velocity 02m/sec at every point within the pipe intake area. at x=1, the rightward flow rate is 0.192 m/sec. assume the water is a conserved quantity in the pipe, so there must be a leak (a sink) somewhere in the pipe. 1. compute net volumetric flow of the source if the system to be in equilibrium. 2. now assume the pipe in the problem has no leaks. compute the net volumetric rate of change for the system.
