Consider a spherical capacitor that is connected with a battery (not shown in the figure) consists of a solid spherical conductor and a spherical shell. The charge at it's core is Q1=32nC and it is Q2=−Q1nC on the spherical shell conductor covering the core (depicted in the figure-1). The solid spherical conductor at the core has radius a=4cm . And the shell has inner radius b=16cm and outer radius c=21cm . The space between the solid spherical conductor and spherical shell conductor is vacuum. Note that, all charges are in nano coulombs. And all coordinates are in centimeters. Given this information, answer the following questions: a) Calculate the potential difference between the solid spherical conductor and spherical shell conductor.

Problem An electric charge Q is distributed uniformly along a thick and enormously long conducting wire with radius R and length L. Using Gauss's law, what is the electric field at distance r perpendicular to the wire? (Consider the cases inside and outside the wire) Solution To find the electric field inside at r distance from the wire we will use the Gauss's law which is expressed as DE - dÃ= Q piR2L We will choose a symmetric Gaussian surface, which is the surface a cylinder excluding its ends, then evaluate the dot product to obtain E A = qenc / epsilon0 (Equation 1) Case 1: Inside the wire Since, r falls inside the wire, then all the enclosed charge must be: qenc = Qr2/R2 On the other hand, the Gaussian surface inside the wire is given by A = 2pirL Using Equation 1, the electric field in simplified form is E = Qr / 2piR2Lepsilono Case 2: Outside the wire Since, r falls outside the wire, then, all the charge must be enclosed, thus qenc = On the other hand, the Gaussian surface…
