Unformatted text preview: EE1259: Electromagnetic assignment 1 EE1259 Assignment 6 (Due on 9:00am Thursday, October 18, 2007) 1. A conducting sphere of radius a is half-embedded in a liquid dielectric medium of permittivity 1 as shown in the figure. The region above the liquid is a gas of permittivity 2 . If the total free charge on the sphere is Q, determine the electric field intensity everywhere. 2. Given that z y x a a a E r r r r 12 6 10 1 + = V/m, find: (a) P 1 , (b) E 2 and the angle E 2 make with y-axis, (c) the energy density in each region. 3. Two parallel sheets of glass ( r =8.5) mounted vertically are separated by a uniform air gap between their inner surface. The sheets, properly sealed, are immersed in oil ( r =3.0) as shown below. A uniform electric field of strength 2000 V/m in the horizontal direction exists in the oil. Calculate the magnitude and direction of the electric field in the glass and in the enclosed air gap when (a) the field is normal to the glass surfaces, and (b) the field in...
