An infinitely long line charge of uniform "near charge density λ--280 μc/m lles parallel to the y axis atx·-1.00 m. a point charge of 5.00 pc is located at x-2.50 m, y-3.50 m find the electric field atx-3.50 m, y 3.00 m

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.
