Unformatted text preview: a , with the center of the circle at the origin. “Thin” means that it can be treated as if it had line charge density ρ l and the radius of the wire can be treated as if it were 0. A charge Q is placed on the wire. a) Derive the voltage and the electric ﬁeld on the z-axis ( x = 0 ,y = 0). above the wire. b) Find the voltage and electric ﬁeld on the z-axis ( x = 0 ,y = 0) if the wire is replaced with a thin metallic disk of radius a and the same charge is placed on it. c) Does the disk produce a larger electric ﬁeld at (0 , ,z ) than the wire? 1...
