Question 28 (1 points A positive charge Q = 1.3 x 10- C is located along the x-axis at x = -10 m, and a negative charge of the same magnitude is located at the origin. What is the magnitude and direction of the electric field a tthe point along the x-axis where = +10-3 m? (Use Coulomb's constant k = 9 x 10 Nm2 / C2 and to the right as the positive direction)
