Three point charges are located at the corners of an equilateral triangle as in Figure P15.13. Find the magnitude and direction of the net electric force on the 2.00 µC charge.

Struggled with this problem for 2 hours, and this helped me finally get it right, thank you so much.

Love the simplification of this. Unlike most it seems, I've got a great physics prof. But dumbing things down even further like this makes things a lot easier.

good video explaination, the different colors for the forces on each charge really helped

[michaelberthaud]

in some problems when finding the component you switch what trig function you use to find the components in this one you use sin for the x component why wouldn't it be Cos doesn't cos usually correspond with x?

[bayandakwezi]

i think the procedure to do this is helpful and correct .. but the answers are wrong answers... why Fx has to be 3.6 yet when you calculate what is visible on the video you get 5.36 ?

Great video, it would be also nice though to see the actual numbers at 5.06. I do not know why but for some reason I keep getting the wrong answer for the sum of the x forces even though my calculator is in degree mode.

Hi, could you show out the working for the sum of fx? I couldnt get 3.6 x 10^-2

[geoffphillips]

Thanks to you, I now fully understand these kinds of probs, thnx so much 😀

[mentalsiege]

Isn't cos associated with the x axis and sin with the y axis?

[unknown-mnwo]

For some reason my brain thought I should find the electric field and I spent an extra 30 minutes trying to figure out what I did wrong before I read the question again

[leagueofmozu]

what if we calculate the net force on 7x10^-6 C ? how do we get it?

[fornx]

This man is clearly a god. Thank you sir!!!

[kevinhicks]

The actual answer for the sum of Fx is .756N. I don't know why you have it as 0.036.

Three charges A(4 µC), B(-6 µC) and C (2 µC) are placed at the vertices of a right angle triangle
ABC. AC = 10 cm, BC = 6 cm. Find the net force on charge B due to Charge C and A.

[alikhan-bnld]

Is it necessary to put cosϴ and sinϴ while calculating ∑fx and ∑fy or can we calculate them without involving Sin and Cos in this by the taking the product of Coulomb's constant and charges??
Please tell me!

[CIXPIYB]

I thought the Y-axis usually takes the sin trigonometry

[waseemmaqbool]

this is good but i want you to upload some video of a problem when one of the charges is removed.plz

[gboyegaoluwatobiloba]

Very unexplanatory. How did you arrive at the Fx, you should take your time to break things down.

[Sam]

What if you want to find the electric field at a point midway between A and B?
