Homework Statement
Consider three charges at the vertices of an equilateral triangle of side a = 7 cm. qA = +2 µC, qB = +2 µC, and qC = 1 µC. (see attached picture)
Find the x and y components of the electric force acting on qC
Homework Equations
i am doing everything right, but getting wrong answer ???
The Attempt at a Solution
xcomp cancel obviously, so im left with finding ycomp...
F = kqAqC/r^2
= 2.571e1
sin60(2.571e1) = 2.2266e1
multiply by 2 = 4.453e1 N (this is wrong though)
i cant see the prob. The forces both point in positive y direction, so the y vectors sum
please help, thanks!
