11.Consider a hollow thin conducting sphere of radius R = 10 cm, uniformly distributed with a surface charge density of σ = 10-9 coulombs/cm2. a) Find the field at a radius r > 10 cm. Explain the vector orientation of the field and the magnitude. b) Find the field at a radius r < 10 cm inside the sphere. Explain the vector orientation of the field and the magnitude. c) Now consider two concentric conducting spherical shells, each coated with a uniformly distributed surface charge density of σ with R1 = R and R2 = R/2. Find the field at all r.
