You start with Coulomb's Law:
F=kq1*q2/distance^2 then
f/q2= E= kq1/distance^2
YOu have q1, and distance from origin to x1. Calculate.
Now if there were a y position, say 10cm, then you could do it two ways>
find distance=sqrt(x^2 + y^2) or
just find Ex due to x position, and Ey due to y postion, then
E= sqrt (Ex^2 + Ey^2)
A 55 uC point charge is at the origin. Find the electric field at the point x1 = 60 cm,y1 = 0cm . I have no idea where to start can someone help me?
