Find where a third charge would be in equilibrium | Electric charges & fields | Khan Academy

Let's solve a numerical and see how to figure out where the null point is. Null point is where the net electric fields due to all charges add up to be zero.

This was exactly what I was looking for. The logical deduction really helped simplify things. Great teaching skills!

[@sarwagyaacharya419]

THANK YOU SO MUCH. THE EXPLANATION WAS CRYSTAL CLEAR

[@ashutosh-kumar]

Thank you sir, watched it on 11 October 2021 at 01:40 AM for the prepration of my term 1 board examination 2021-2022.

Please do upload frequently, covering Short answered numericals for term 1 CBSE, we need teachers like you in this uncertain time.I have already watched all your lectures covering complex topics that otherwise I would have crammed for the exams, now I understand them intuitively. Thank you so much 🙏

Thank you for this great explanation, earlier I wasn't able to understand the logic behind where to place the third charge incase of opposite - sign charges but now I get it!

🥺sir we students were waiting for your lectures since eternity ❤️❤️❤️❤️❤️❤️plz uplaod more of physics lectures before our Term1. Meanwhile, am watching the already uploaded ones amazed at every concept made so simple😊❤️

[@ukwumaifunanya-mz3ky]

Thank you sir What if you are asked to find the quantity of the third charge

[@HenryMasamba-f4v]

Excellent

[@captainamerica150]

Use the formula x=d/(√q2/q1)±1. If it's a positive charge then use +1and if it's negative charge then use -1

[@yashkendre1311]

Best 👍 explanation.

[@AfomiyaGashuMulu]

Thank you very much! but what if the two opposing charges have the same magnitude where will be the electric field 0 as i think in this case there is no way for the electric field to be 0

[@RadonOganesson]

Amazing as always

[@orangeinfotainment620]

thank you!

In this video, I observed your voice quality improves a bit than your older video. Either you might have shifted to new equipment or your accent is getting better day by day.
