A1250kg car is moving down the highway with a velocity of 32.0m/s when it bumps into the car ahead of it, which has a mass of 875kg and a velocity of 25.0 m/s

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.)
