I think you want to find Fnet A ...

Triangle diagram of three point charges: A at -2 µC at the top, B at 3 µC at bottom left, C at 1 µC at bottom right, with 1 m labelled on sides AB and BC. Red arrows show forces F(B on A) and F(C on A) acting on charge A, with green components drawn.

Two equations: F_net,x = F_AC cos(π/4) and F_net,y = F_AB + F_AC sin(π/4).

Two typeset equations: F_net,A = sqrt(F_net,x^2 + F_net,y^2) and theta = tan^-1(F_net,y / F_net,x).

Tell me which part you need explanation.

Homework Statement:: Find the net force of A as shown in the diagram.
Relevant Equations:: FAB=KqAqB/r2
Fx=Fcosθ
Fy=Fsinθ
FR=square root of the total of Fx^2+the total of Fy^2
θ=tan-1(Fy/Fx)

Find the net force of A as shown in the diagram.

You need to find the vector forces ## F_{AB} ## and ## F_{AC} ## and sum those force vectors to get the total force on A. Can you show us your work on that?
