In figure two positive charges, $q_2$ and $q_3$ fixed along the y-axis, exert a net electric force in the $+x$ direction on a charge $q_1$ fixed along the x-axis. If a positive charge $Q$ is added at $(x,0)$, the force on $q_1$:

1) Two positive charges q1=q2=2.0uc are located at x=0, y=0.30m, respectively. what are the magnitude and direction of the total electric force that q1 and q2 exert on a third charge Q=4.0 uc at x=0.40m, y=0?

2) suppose that charge q2 in question no 1 were (-2.0)uc in this case, the total electric force on q would be 1) in the positive x-direction; 2) in the negative x-direction; 3) in the positive y-direction; 4) in the negative y-direction; 5) zero; 6) none of these.

Two equal positive point charges q1 = q2 =2.0 μC are located at x = 0, y = 0.30 m and x = 0, y = --0.30 m, respectively. What are the magnitude and the direction of the net electric force that these charges exert on a third point charge Q = 4.0 μC at x = 0.40 m, y = 0?

Two positive charges $q_1$ and $q_2$ are moving with velocities $v_1$ and $v_2$ when they are at points $A$ and $B$, respectively, as shown in figure. The magnetic force experienced by charge $q_1$ due to the other charge $q_2$ is :
