Question
problem 26: A point charge is a distance d from the origin on the z-axis. Consider two circular regions each with area A in the x- y plane. Region I is centered on the z axis and region Ills a distance d along the x-axis. How does the density of electric field lines compare for the two regions? select One of the Following: (a) The density of electric field lines is the same for both regions. (b) The density of electric field lines is greater for region I. (c) The density of electric field lines is greater for region II. blem 27: The two thin concentric spherical shells each have uniform surface char densities. The total charge on the inner shell is + Q and the total char on the outer shell is - Q Which of the following best describes direction of the electric field between the shells? Select one of the following: (a) The electric field between the shells point radially outward fromExplanation / Answer
Problem 26
Answer: Density of electric field lines is greater for region I.
Since region II is far away than region I from the point charge, the electric field intensity at region I is greater than that at region II. Greater the intensity, greater is the field line density.
