When you must add three vectors together, what is not true this process? You must only give a magnitude of the resultant vector It does not matter what order you add the vectors You can move the vectors parallel to each other You must connect the head of each vector with the tail of the next vector

Point charges q1=+2.00μc and q2=−2.00μc are placed at adjacent corners of a square for which the length of each side is 1.50 cm . point a is at the center of the square, and point b is at the empty corner closest to q2. take the electric potential to be zero at a distance far from both charges. part a what is the electric potential at point a due to q1 and q2? express your answer with the appropriate units.
