(1) A charge of 80 nC IS UNIFORMLY DISTRIBUTED ALONG THE X AXIS FROM X=0 TO X=2.0m determine the magnitude of the electric field at a point on the x-axis with x=8.0m

(a) 30N/C

(b) 15N/C

(c) 48N/C

(d) 90N/C

use dx charge distribution from 0 to 2 which is to be used as limits of integration 

then use the coulombs law by taking d=x+dx

then integrate to get the answer

sorry i dont have a pen now so try it urself
