OP warned about not using the homework template
How do you calculate compute the the magnitude of the total force of three charges and also the angle it makes with the x-axis? Knowing the magnitude and also the 2d co ordinates of the charges.
I have deliberately not given any specific values because this is not homework its a question from old exam paper and I want to know how to do it because I have a gut feeling it will be on the mid term and I honestly don't know what to do so if somebody could give me a step by step that would be great!
The only thing I know for definite I use the below formula but that's the only a clue I got from my tutor but I don't know how to use it I don't even know where to start I have no examples or anything.
K0 * Q1.Q2 / d^2 * r hat Thanks :)
