Question

Draw the electric field that corresponds to the equipotential surfaces shown in the following figure. Note that the potential is decreasing in the upward direction.

Accepted Answer

Alright, guys, hopefully you try this practice problem out on your own. We're gonna get a little bit more practice withdrawing electric field lines from equal potential surfaces. Remember? So we have these equal potential surfaces were not told what the numbers are, but we can figure out what the electric field points. Remember that there's two rules to follow. The first is that these electric field lines are always gonna be perpendicular to the echo potential surfaces. And the second one is that they're always going to point towards decreasing potentials in this, uh, this figure here, we're told that the decreasing potentials is along the upward direction. We're not told the numbers are, but we just do know that the potential decreases upwards. So following our rules, the electric field lines are gonna always be pointing perpendicular to those eco potential services. And they're always going to point towards decreasing electric, start decreasing potentials. So that means these things always have to be perpendicular and they're just going to point upwards. So you just have to make sure that when you're drawing these, that you're drawing them correctly, so always be perpendicular and then always go towards decreasing potentials, and that's basically it. So the electric field lines are gonna point in this direction over here. Let me know if you guys have any questions with that.
