A uniform electric field E =-3.4N/Ci points in the negative x direction as shown in the figure. The x and y coordinates of points A, B, and C are given on the diagram (in meters).
A at (4,1), B at (4,4) and C at (-3,4).
Determine the differences in potential VBA=VB-VA, VCB =VC-VB, and VCA=VC-VA
A thin cylindrical shell of radius R1=6.5cm is surrounded by a second cylindrical shell of radius R2=8.7cm, as in the figure . Both cylinders are 12 m long and the inner one carries a total charge Q1=-0.87μC and the outer one Q2=+1.47μC
For points far from the ends of the cylinders, determine the magnitude of the electric field at a radial distance r from the central axis of 7.0 cm
For points far from the ends of the cylinders, determine the magnitude of the electric field at a radial distance r from the central axis of 13.2 cm
