Again, find C. 3) (a) Find the electric field ( E ) on the zaxis for z = h > 0 ? (b) Find the electric field ( E ) on the zaxis for z = k where k<d? (c) Find the electric field ( E ) on the zaxis for z = k where k>d? 4) Find the capacitance of an isolated conducting sphere of radius b that is uniformly coated with a dielectric layer of thickness d. The dielectric constant is given by ε ....
