An average human weighs  about 600 N.  If each of two average humans could carry 2.5 C of excess charge, one positive and one negative, how far apart would they have to be for the electric  attraction between them equal their 600 N  weight?

Three negative point charges lie along a line as shown in the figure. Find the magnitude and direction of the electric field this combination of charges produces at point P, which lies 6.00 cm from the -2.00uC charge measured perpendicular to the line connecting the three charges.
