Apoint charge is at the origin. with this point charge as the source point, what is the unit vector r^ in the direction of (a) the field point at x = 0 , y = -1.35m; (b) the field point at x = 12.0cm, y = 12.0cm; (c) the field point at x = - 1.10m, y = 2.60m? express your results in terms of the unit vectors i^ and j^. you may want to review (pages 695 - 699) . for related problem-solving tips and strategies, you may want to view a video tutor solution of electric-field vector for a point charge.
