Question

Multiple-Choice Homework Problem 3.6 A 2.OnC point charge is located at the point = (-3.0cm, -4.0cm, 5.0cm). Compute the electric field at the point P at rp = 5.0cm x + 1.0cmy. Multiple-Choke Homework Problem 3.3 A field map s shown to the right, the dashed region contains a distribution of charge. Select one of the following that best describes the distribution of charge. Select One of the Following: (a) monopole system, positive net charge (b) monopole system, negative net charge (c) dipole system, dipole moment toward the left of page (d) dipole system, dipole moment toward the right of page (e) dipole system, dipole moment toward the top of page (f) dipole system, dipole moment toward the bottom of page

Explanation / Answer

3.3)

For a positive charge the electric field lines are directed away from the charge and for a negative charge the electric field lines are directed towards the charge.

So one can conclude from the figure that the given system is dipole, and in a dipole the electric field lines originate at positive charge and ends at negative charge. The dipole moment always directed from positive charge to the negative charge.

Therefore, the given system is a dipole system with dipole moment toward right of the page.
