How can you complete electric field lines between -3 micro coloumb and +5 microcoloumb?

 

On the other hand, positive charges, +5 micro coulombs in this case, are where the electric field lines originate or begin. The field lines radiate out from the positive charge. Here, given that this charge is greater than the negative charge, more field lines will originate from this charge.

The pattern of these lines also suggests the interaction between these two charges. They would move along the electric field lines from the positive charge towards the negative charge, representing the motion of a positive test charge if it were released near the positive charge. Since field lines are denser closer to the charges and less dense further away, this indicates that the electric field is stronger near the charges and weakens with increasing distance.

Moreover, these field lines never cross each other. Each line must begin on a positive charge and end on a negative charge, making an unbroken curve. It is crucial to keep in mind this fundamental concept while drawing electric field lines.

When the magnitudes of charges are different, the spacing between lines can be tricky. Electric field strength is proportional to the number of field lines per unit area perpendicular to the lines. Therefore, there should be more field lines originating from the positive charge, implying a stronger field in that region. On the contrary, the area around the negative charge will have fewer field lines indicating a weaker electric field in that area.

Lastly, the direction of the electric field at any point in space is tangent to the field line at that point. Thus, in a simple setup with only two charges, electric field lines will generally form a series of lines that emerge from the positive charge and curve towards the negative charge. Remembering this guideline will help you accurately draw or complete the electric field lines between -3 micro coulomb and +5 micro coulomb charges.
