A -11 nC charge is located at (x, y) = (0.80 cm , 0 cm).
Part A:
What is thex-component of the electric field at the position
(x,y) = (4.4 cm , 0 cm)?
Part B:
What is the y-component of the electric field at the
position (x, y) = (4.4 cm , 0 cm)?
Part C:
What is thex-component of the electric field at the position
(x,y) = (4.4cm, 0 cm)?
Part D:
What is the y-component of the electric field at the
position (x, y) = (4.4cm, 0 cm)?
Part E:
What is thex-component of the electric field at the position
(x,y) = (0 cm, 4.4 cm )?
Part F:
What is they-component of the electric field at the position
(x,y) = (0 cm, 4.4 cm )?
Parts A-D I got correct, E and F are what I need help with.
Answers to A-D
A: -7.6x10^4 N/C
B: 0 N/C
C: 3.7x10^4 N/C
D: 0 N/C

Solution
The point (x1,y1)=(0 cm, 4.4 cm)
charge is located at (x, y) = (0.80 cm , 0 cm).
let x0=0.8
let y0=4.4
Electric field(E)= k*q/r^2
q=-11nc
r= sqrt(x0^2 + y0^2)
Electric field at (0 cm, 4.4 cm) (E)= kq/r^2
But this this electric field is towards the charge. SO we
have to make it into two components(x and y components)
x component = E * sin(t)
y component = -E * cos(t)
sin(t) = x0/r
cos(t) = y0/r
E)x-component of the electric field at (0 cm, 4.4 cm)=
k*q*x0/r^3
F)y-component of the electric field at (0 cm, 4.4 cm)= -
k*q*y0/r^3
Note : I hope you can do the calculations.
Have a nice day.
