Long Answer (25 points) Four point charges are arranged at the corners of a square of side length a=15.0 cm as shown in the figure. a=15cm q? = +10 nC q? = +18 nC $\vec{F} = \vec{F}_1 + \vec{F}_2 + \vec{F}_3 + \vec{F}_4$ q? = -10 nC q? = +18 nC A. Determine the magnitude and direction (expressed as a field strength and angle) of the electrostatic force on a 5th charge with q? = +25 nC placed at the center of the square. B. Determine the amount of work necessary to move q? from infinitely far away to its position at the center of the square.
