Oc and qo are two point charges, -16.0 nc and +4.0 nc, respectively, fixed 10 meter apart. point p, is located exactly halfway between them. a.(3 pts) sketch e-field lines surrounding the charges be low. include arrowheads to indicate direction. (8 pts) you may solve (b) and (c) in whichever onder you wish, but show your work clearly: b. calculate the magnitude and direction of the total e-field at point p c. if an electron were placed at point p, what would be the magnitude and direction of the electrostatic force on it? d. (i pt) imagine a line passing through the centers of q, and q and extending outw ard to either side. find the one position along this line where an electron would feel a net electrostatic for ce of zero. do not solve for the exact position: just mark its apptoximate location on the page with a point labeled "p, (hin: p, is not necessarily located between qc and qp)
