Hint 5.Putting it all togetherInformation about the electric field at a particular point was given in the introduction, so the potential differencebetween the wire and the cylinder can now be calculated at that point.
CorrectIt is also possible to find the potential difference between the inner wire and the outer cylinder by integrating theelectric field fromto, and then fromto, using the givenvalue of the field atas an intermediate integration limit. However, this is much more difficult to do,since the charge per unit length on the wire is not known, and is not necessary if you instead find an expression forthe electric field in terms of the potential difference.
Hint 4.Find a new expression for the electric fieldUsing the equation for the potential differencethat was found in Hint 3, rewrite the expression for theterms of electric fieldand the radial distanceExpress your answer in terms of some or all the variables,,,, and any appropriate constants.in.
