Fill in the blanks. (a) (1 point)The direction of the electric field is defined as the direction that a _____________________ test charge would move. (b). (4 points) If a point charge moves at constant velocity x v v o = r into a region of constant electric field, z E E o = r , the path of the charge will be a ________________________________. How would the path change if the sign of the charge were to be reversed?__________________________________________ 2.
