Two square metal plates are placed parallel to each other, separated by a distance d= 2.28 cm. the plates have sides of length l = 0.690 m. one of the plates has charge q= + 2.34×10-6 c, while the other plate has charge -q. calculate the magnitude of the electric field between the plates, not close to the edge, i. e., assume a uniform surface charge distribution.

when insulating materials rub against each other, they may become electrically charged . electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. the material that gains electrons becomes negatively charged. the material that loses electrons is left with a positive charge.
