Question Completion Status: QUESTION 6 The figure to the right shows an infinite plane of uniform positive charge in the r-z plane. The plane is drawn in gray. Four points are drawn around the plane. Points (b), (c), and (d) are a distance d from the plane. Point (a) is a dis- tance 2d from the plane. Rank the magnitude of the electric field, E. at the four points. Select One of the Following Answer (a) Answer (b) Answer () Answer (d) Answer (e) QUESTION 7 k Save and Submit to save and submit, Click Save All Answers to sove all answers

Explanation / Answer

electirc field due to infinite charge sheet is E = sigma/(2*eo)

sigma is the surface charge density

eo is the permittivity of free space

the electrioc field does not depend on distance ,it depends only on charge and surface area only

so the answer is Ea = Eb = Ec = Ed

so correct choice is answer a)
