1. First draw a picture of the situation, so that you can see where these charges are located on the Cartesian Plane, and the angles involved.
2. Use Coulomb's Law:
Force of q1 on q3 (it pushes q3 away)
F1= (kq1q3)/(r)^2
Force of q2 on q3 (it pulls on q3)
F2 = (kq2q3)/(r)^2
3. Draw a FBD of these two forces acting on q3. Sum forces in the x direction and then in the y direction to get a single force for each. Find the resultant magnitude and direction of the x,y-direction forces using trig, as usual.
a charge q1=5.00nc is placed at the origin of an xy-coordinate system ,and a charge q2=-2.00nc is placed on the positive x-axis at x=4.00cm (a.) if a third charge q3=6.00nc is now placed at the point x=4cm, y=3.00cm. find the x and y components of the total force exerted on this charge by the other two. (b.) find the magnitude and direction of this force.
