(x,y) axis in meters(adsbygoogle = window.adsbygoogle || []).push({});

q1=60microC (0,1)

q2=-34microC (2,0)

q3=13microC (2,2)

Fx3=? Fy3=?

i used superposition

F(net on 3)=F13+F23

broke it down into x and y components

Fx=(kq1q3/r13^2)(x/r13)

Fy=(kq1q3/r13^2)(y/r13) - (kq2q3/r23^2)

plugging in the numbers i got

Fx=1.3

Fy=-0.4

mastering physics says its wrong, and I can't seem to figure out where I went wrong....any suggestions?
