Question

Learning Goal: To practice Problem-Solving Strategy 27.1 for Gauss's law problems An infinite cylindrical rod has a uniform volume charge density p (where p> 0). The cross section of the rod has radius ro. Find the magnitude of the electric field E at a distance r from the axis of the rod. Assume that r ro. Part C Find the magnitude E of the electric field at a distance T from the axis of the cylinder for T To. Keep in mind that we've chosen the label l to represent the length of the cylindrical Gaussian surface Express your answer in terms of some or all of quantities p, T, ro, l, and eo. Submit Hints My Answers Give Up Review Part incorrect; Try Again; 4 attempts remaining; no points deducted The correct answer does not depend on: p Assess

Explanation / Answer

We take a cyclindrical structure of length L arounnd this rod at radius r

Now using guass law,

E.A = qin / e0

E (2* pi * r * L ) = (row * L * pi * r^2) / e0

E = row * r / 2e0
