Question

k = 8.00 times 10^9 N m^2/C^2. Compute with symbols first and plug in number at the end. Four Gaussian surface are drawn in the field of two opposite charges of equal magnitude as shown. Rank the electric flux through surfaces S_1 TO S_4, greatest first. Two infinite parallel plates ram- charge densities plusminus sigma, respectively. What is the electric field in each of the three regions: i) to the left, ii) in between, and iii) to the right, of the plates? Also sketch the magnitude of the electric field as a function of x across the regions.

Explanation / Answer

1.

S4, S2, S1 and S3 , since Electric Flux us given by E.dA and also gives an idea regarding total number of lines passing through the surface.
