Which of the following correctly describes the result
charges move randomly
charges do not move
charges flow from low voltage areas to high
charges flows from high voltage areas to low

Charges flows from high voltage areas to low

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)
