Question
Could i get help on both multiple choice questions. Have an idea of what it is. I just would like some confirmation and an explanation as to why it's that answer.
Homework 4 (2pts)what is then ax and electr the two charges below? ie field on the surface of the Gaussian sphere surrounding Gaunsiana) flux enclosed is zero, electric field on surface is zero urtar b) flux enclosed is zero, electric field on surface is parallel with surface normal c) flux enclosed is zero, electric field on surface is perpendicular to surface normal d) flux enclosed is nonzero, electric field on surface is zero e) flux enclosed is nonzero, electric field on surface is parallel with surface normal 0 flux enclosed is nonzero, electric field on surface is perpendicular to surface normal g) none of the above Explain briefly: pts)Two students are working similar problems using Gauss' law: Trying to find the electric field 4-cm from the center of a uniformly charged cylinder (that is very long). The only difference between the two problems is the radius of the cylinder, How should the electric field at each Gaussian surface compare? 2. (2 Set-up A radius 1 em charge/m 75 C/m Set-up B radius 2 cm charge/m 75 C/m Explain briefly: d) Can not determineExplanation / Answer
1.
Answer would be E.
The flux enclosed would be non zero and field on surface is parallel to surface normal which makes the angle between them zero and makes cos(0) = 1 (in E. ds dot product )
2.
Answer would be B
As the surface area of the gaussean surface is same and charge per meter is same (that is h in both cases) which means charge enclosed is same and radius is same
Electric fields will be same.
