As you look at the above image, determine (i) the direction of the electric field, and (ii) the likely charge on the Page 5: molecules in the sample if they are to move in the direction shown in the image. 13 14 15 (i) The electric field is directed from the positive electrode to the negative electrode; (ii) Negatively-charged molecules would move away from the Page 6: negative electrode, through the gel, and towards the positive electrode. 16 17 18 (i) The electric field is directed from the positive electrode to the negative electrode; (ii) Positively-charged molecules would move away from the negative Page 7: electrode, through the gel, and towards the positive electrode. 19 20 (i) The electric field is directed from the negative electrode to the positive electrode; (ii) Negatively-charged molecules would move away from the negative electrode, through the gel, and towards the positive electrode. (i) The electric field is directed from the negative electrode to the positive electrode; (ii) Positively-charged molecules would move away from the negative electrode, through the gel, and towards the positive electrode
