Tutorial-3 Gauss’s Law and Electric Flux Density Learning Outcomes: After successful completion of this tutorial students will be able to: 1. Compute electric flux density for a given charge distribution 2. Apply Gauss law to determine electric field intensity using symmetric/asymmetric Gaussian surfaces Q. 1 A point charge of 20nC is located at (4,-1, 3), and a uniform line charge of -25 nC/m lies along the intersection of the planes x=-4 and z=6. (a) Calculate D at (3,- 1, 0). (b) How much electric flux leaves the surface of a sphere of radius 5, centered at the origin? (c) Repeat part b if the radius of the sphere is 10. −0.38 ax + 0.13 az nC/m2, zero, −326 nC Q. 2 The cylindrical surface ƍ = 8 cm contains the surface charge density, ƍs = 5e-20|z| nC/m2. (a) What is the total amount of charge present? (b) How much electric flux leaves the surface ƍ=8 cm, 1 cm < z < 5 cm, 30°
