i don't even have the time to make a comment on ALL the magnificent videos you put together, but I MUST say...they are THE VERY BEST. tytytytyty for saving my butt this semester.
Thanks Wny tutor.when our teacher learn us coloumbs law i don't understand the direction matter.but after see ur video i totally understand this.Thnq So much Brother 🤗🤗
when you calculate F(BA). where does the negative sign go? i keep getting -43.15 (F BA) and for F (CA) i get 89.9. so when i subtract -43.15 - 89.9 i get -133.05 for my answer
This all makes sense except for what if you’re only given Q1 and Q2 their distance in you’re trying to decide where Q3 is located given that the net charge on Q1 is 7 N in the negative direction
Since they particle A has different directions when interacting with different particles, it should be subtracted, right? Then, how do I know that it should be F(ca) minus F(ba) and not the other way around?
Remember to apply the Principle of Superposition , also these charges are "nailed down" and are assumed to not move (electrostatic) so that you can calculate the magnitudes of the forces.
Its ok and simple i have another probleme would someone help me with it we have a straight line that have a distance of 2a in the corners of the line there is a charge q + and in the other side also q+ in the middel of the line there are 2 times 2q that are flexible and can move to the right and to the left and the question is where will the 2q and the other 2q will stay stable i mean equalibrium Small tip is givin X^4-8x^3-2x^2+1=0 This equation has 2 real solution that are X1= 0,4348 X2= 8,2409 If anyone has a idea please help me im confused i dont know how to solve this problem we had an exmple of a straight line but in the middel was only 1 2q and we had tp find out where the equalibrium is and that was ok but with 2 times 2 q i dont come at the tip

Bless up! Thanks for helping me pass physics last semester my dude! I'm counting on these videos to get me through second semester. U the truest
Spring 2021 Physics 2 students where you at?

Still so confusing about how forces act on each other, but must say thank you for the effort.
when you calculate F(BA). where does the negative sign go? i keep getting -43.15 (F BA) and for F (CA) i get 89.9. so when i subtract -43.15 - 89.9 i get -133.05 for my answer
He has it switched you basically do 89.9-43.15 to get your answer
Remember that in Coulomb's law you're using absolute value, that is why he gets 46.7 because the |-2.00 x 10^-6| becomes positive.
If he used the absolute value, then why is it -46.7 and not 46.7? I'm quite confused.
you're a life saver thank you so much!!!
You're welcome!
How to know if it is subtraction or addition to get the Net force like for example why is it in charge C we add FBC+FAC?
best illustration ever. i finally understand
how you determine direction for resulting force
Like charges repel each other so if both positive then it is away from the other force.
why to the left is considered negative?
What is an easy way to get the direction of a net force or Electric field on an X-axis without numbers?
Why are the lines pointing away from the negative charge?
It means they are repelling
legend!
Thanks for watching!

That went over my head

Tq....its super easy ..I understood
But electric fields are always move from negative charge to positive and also electric fields direction is always directed to the force direction
If we subtract Fca and -Fba wouldn't it be Fca-(-Fba)=Fca+Fba?
Exactly my doubt
I got the correct answer when I changed minus to plus. Lol
how do you know which magnitude is higher?
awesome video!
thank you !
Nice video, very helpful.
Its ok and simple i have another probleme would someone help me with it we have a straight line that have a distance of 2a in the corners of the line there is a charge q + and in the other side also q+ in the middel of the line there are 2 times 2q that are flexible and can move to the right and to the left and the question is where will the 2q and the other 2q will stay stable i mean equalibrium
Small tip is givin
X^4-8x^3-2x^2+1=0
This equation has 2 real solution that are
X1= 0,4348
X2= 8,2409
If anyone has a idea please help me im confused i dont know how to solve this problem we had an exmple of a straight line but in the middel was only 1 2q and we had tp find out where the equalibrium is and that was ok but with 2 times 2 q i dont come at the tip
saving my ass on a exam, ty
Great work !!
❤❤❤
THANK YOU
Thanks m8.
