D3.5. A point charge of 0.25 µC is located at r = 0, and uniform surface charge densities are located as follows: 2 mC/m² at r = 1 cm, and -0.6 mC/m² at r = 1.8 cm. Calculate D at: (a) r = 0.5 cm; (b) r = 1.5 cm; (c) r = 2.5 cm. (d) What uniform surface charge density should be established at r = 3 cm to cause D = 0 at r = 3.5 cm? Ans. 796a, µC/m²; 977a, µC/m²; 40.8a, µC/m²; -28.3 µC/m²
