Final answer:
The electric field representation for two objects with equal magnitude charges of opposite polarity is shown by lines starting at the positive charge and ending at the negative charge, indicating the force on a positive test charge. The lines are symmetric for equal charges, while asymmetrical with varied line densities for unequal charges.
Step-by-step explanation:
Characteristics of Electric Field Lines
The question pertains to the representation of electric field lines surrounding two objects with equal magnitude charges of opposite polarity. To visualize this scenario, one would draw a set of electric field lines emanating from the positive charge and terminating at the negative charge. The lines would curve outward from the positive charge and curve inward towards the negative charge, indicating the direction of force that a positive test charge would experience in the field.
When the charges are of equal magnitude but opposite in nature, the electric field lines are symmetric with respect to the line joining the two charges. The density of the lines would be the same at equal distances from both charges, reflecting the equal magnitudes and indicating the strength of the field. If the charges had different magnitudes, the lines would be more concentrated near the larger charge.
For charges that are not equal in magnitude, such as a case with a negative charge three times greater than a positive charge, the electric field lines would begin at the positive charge and end at the negative charge with a greater density of lines near the negative charge. This shows that the field strength is greater near the larger charge, and the lines should be drawn to reflect this asymmetry.
