Hello everyone and I hope you are enjoying your weekend. I am currently studying for my college physics midterm and got hung up on one of the problems that was on an old midterm.
The problem is as follows: Point charges Q1 = -5uC(micro C) and Q2 = +5.5 uC(micro C) are placed 0.4m apart as shown. The picture shows a 0.4 meter line pointing East, with the positive charge(Q2) on the right and the negative charge(Q1) on the left. Right above Q1, a 0.3 meter line goes North and ends at a point called P.
The drawing is pretty much a right triangle without the hypotenuse line drawn in.
The question wants me to calculate both the x and y components of the total electric field vector at point P. I have one vector line going South and the other going Northwest because of the positive charge. The problem does not give any angles so I'm not sure if they want me to find them or not?
Should I use E = kq/r^2? or Coulomb's Law? I greatly appreciate people for looking at this. I know most of the other problems on this midterm except this one!
