Question: Let D = 5.00r 2 a r mC/m 2 for r 0.08 m and D = 0.205 a r /r 2 C/m 2 for

Let D = 5.00r2ar mC/m2 for r ≤ 0.08 m and D = 0.205 ar /r2 μC/m2 for r ≥ 0.08 m.

(a) Find ρν for r = 0.06 m.

(b) Find ρν for r = 0.1 m.

(c) What surface charge density could be located at r = 0.08 m to cause D = 0 for r > 0.08 m?
