Okay, so all of the charges are negative. So between the middle (main) charge and the left charge, it wants to move right. Between the middle and the charge to the right of it, it wants to move left. The magnitude of the electrostatic force of the middle charge and the left charge is 135N. The...
Homework Statement
A particle with charge −8 μC is located on the x-axis at the point 8 cm, and a second particle with charge −6 μC is placed on the x-axis at −6 cm.
What is the magnitude of the total electrostatic force on a third particle with charge −4 μC placed on the x-axis at −2...
