Unformatted text preview: The Hashemite University Second Exam Electrical Engineering Department Electromagnetic I second Sem. 07/08 Faculty of Engineering Instructors: Dr. Omar Saraereh Time: 1 hour Q1: Planes x = 2 and y = -3, respectively, carry charges 10 nC/m2 and 15 nC/m2. If the line x = 0, z = 2 carries charge l0Π nC/m, calculate E at (1, 1, -1) due to the three charge distribution. (10 marks) Q2: Derive an expression of the electrostatic field E as a function the electric potential V. (4 marks) Q3: Charge Q1 is uniformly distributed over a thin spherical shell of radius a, and charge Q2 is uniformly distributed over a second spherical shell of radius b, with b>a. Apply Gauss’s law to find E in (6 marks) the regions R<a, a<R<b, and R>b. www.Husni.net ...
