You are very good at teaching. I like how you give a reason after each step such as, "The reason is...""This is because...", This really helps me understand what's going on clearly.
Excellent work! Very pragmatic and empirical… Perfect for non-mathematically and non-physicly minded people which is about 90% of the world population ha ha!
OMG really thanks so much. I am so confused by the electric field and my concept are not good enough Its so thankful that i m now understand how to calculate this now
did you subtract 2.8284-1.7321? it's really confusing if you didn't mention it in the video you know?, but anyway thanks though ;) really help me, but can you help me? anybody? how can i found the distance, or what is the formula when the distance is unknown, in coloumbs law? let say that Q1=42x10^-9C and Q2= 53x10^-9C what is the DISTANCE that will be equal to approximately 7.50x10^4N
Yea, you're right, all there did was subtract 2.8284x - 1.7321x to get 1.0963x. It's the same concept as subtract 4x - 2x to get 2x. I think for your second question, you meant if you have everything except distance? Then you can rearrange the formula F(e) = (kq1q2)/r^2 for r, so it'd be r =√(kq1q2/F(e)). If you're looking for the electric field instead of the electric force, then its just rearranging E = kq/r^2 into r = √(kq/E) for both charges. Or actually, that probably wasn't your question, but I hope after 5 months you've figured it out some other way (:

This has officially saved me! Thank you!!!

This is a really good question for applying theory, thanks!
GrEat sir i m frOm pakistan...aLso student of physics
Would it also be accurate to say it would be 2.57 m from q1?
thanks! I had an idea of how I should work. problem like this but that made it very clear
THANKS A TON!
Thank you!
thanks:D great explanation!!
thank you SO MUCH
I enjoy your lessons, they are very informative, but can you be faster?
Why would you use absolute values?
because you're looking for a point(its magnitude) and magnitudes can never be in a negative form.
excellent

You are awesome!!! Saved my ass
