(d) A third student suggests that the experiment be modified so that the top sphere is given a negative charge that is equal in magnitude to the positive charge given to the bottom sphere. i. On the circles representing the spheres below, use a single \"--\"" sign on the bottom sphere to represent the location of highest concentration of the excess positive charges. Use a single \"\" sign on the top sphere to represent the location of the highest concentration of the excess negative charges. lit B) BIvuavy KX A Boe xX x ii. For a separation distance equal to that of the data point indicated in part (a)(iii), would the magnitude of the force reading with spheres of opposite charges be greater than, less than, or equal to the magnitude of the force reading with spheres of the same charges? Greater than Less than Equal to Justify your
