E field from line charge
WebIt carries charge per unit length +α, where α is a positive constant with units of C/m. A line of charge lies along the axis of the tube. The line of charge has charge per unit length +α. (a) Calculate the electric field in terms of α and the distance r from the axis of the tube for (i) r b. Show your results in a graph of E as a function of R. WebA useful means of visually representing the vector nature of an electric field is through the use of electric field lines of force. A pattern of several lines are drawn that extend between infinity and the source charge or from a source charge to a second nearby charge. The pattern of lines, sometimes referred to as electric field lines, point in the direction that a …

The potential of an infinitely long line charge \(\lambda\) is given in Section 2.5.4 when the length of the line L is made very large. More directly, knowing the electric field of an infinitely long line charge from Section 2.3.3 allows us to obtain the potential by direct integration:
