Aperson starts walking at a constant speed of 2.3 m/s in a straight line from point a to point b . at point b, she turns around and walks back to point a at a speed of 1.1 m/s. what was her average speed for the entire trip in 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.)
