The dot A in Fig. 116 is an end view of a line charge of Qcoulombs per centimeter, and 0 is the chosen region of zeropotential; and it is desired to find the potential at the point p IDEA OF POTENTIAL. 177 distant r centimeters from A.… … zero potential line charge Fig. 116. this by Ax we get the volts along Ax, namely: , „ BQ AxAE =—±.— 2x X (2) and the total volts between 0 and p is found by integratingthis equation from x = 1 to x = r which gives: E =^.logef 27T (3) Now the electric field in Fig. 116 is directed away from 0…
