Question 5.
Given a configuration of three charges (-2μC, +6μC, -2μC) at the corners of a triangle, sketch the electric field lines and explain the pattern.
Show hintHide hint
Draw the direction of lines from each charge and observe their interactions.
Question 6.
If an electric field line configuration shows lines clustering at one point, what can you infer about the charge configuration?
Show hintHide hint
Consider what causes an alteration in density.
