A point charge q1 = -2.1 μC is located at the origin of a co-ordinate system. Another point charge q2 = 6.8 μC is located along the x-axis at a distance x2 = 7 cm from q1.

1)

What is F12,x, the value of the x-component of the force that q1 exerts on q2?
    -26.2285N 
 

2)

Charge q2 is now displaced a distance y2 = 3 cm in the positive y-direction. What is the new value for the x-component of the force that q1 exerts on q2?

 

3)

A third point charge q3 is now positioned halfway between q1 and q2. The net force on q2 now has a magnitude of F2,net = 7.4 N and points away from q1 and q3. What is the value (sign and magnitude) of the charge q3?
