PHYS 2421 Quiz 2 NAME UTEP ID 1. Which of the following statements aboua Gauss's law are correet? There may be more th one correct choice) A) Gauss's cylinders. B) If there is no charge inside of a Gausian surface,the electric field must be zero at poims of that surface C) Only charge enclosed within a Gaussian surface can produce an electric field at points on law is valid only for symmetric charge distributions, such as spheres and athat surface. D) If a Gaussian surface is completely inside an electrostatic conductor, the electric field must always be zero at all points on that surface E) The electric flux passing through a Gaussian surface depends only on the amount of charge inside that surface, not on its size or shape. 2. A charge of 1.0 x 10-6 HC is located inside a sphere, 1.25 cm from its center What is the electric f through the sphere due to this charge? (ro-88S 10-12 c2/N m2) B) 8.9 N m2/c C) 0.028x N m2/C D) It cannot be determined without knowing the radius of the sphere 3. A very large sheet of a conductor carries a uniform charge density of 4.00 pC/mm2 on its surfaces. What is the electric field strength 3.00 mm outside the surface of the conductor? (10-8.85× 10-12 C2/N·m2) 01,452 × 105 NC B) 2.26 x 105 N/C C)9.04 x 105 N/C D) 0.452 N/C E) 0.226 N/CExplanation / Answer
1] option E is correct by definition of Gauss law
2] flux = q/e0 = 1e-6 *10^-6/8.85e-12 = 0.11 Nm^2/C option a
3] E = 2*sigma/2e0 = 4e-12*10^6/8.85e-12 = 4.52*10^5 N/C option a
