Question

A -10nC charge is located at (x, y) = (0.80cm , 0 cm).

What is the x-component of the electric field at the position (x, y) = (5.2cm , 0 cm)?

What is the y-component of the electric field at the position (x, y) = (5.2cm , 0 cm)?

What is the x-component of the electric field at the position (x, y) = (?5.2cm, 0 cm)?

What is the x-component of the electric field at the position (x, y) = (?5.2cm, 0 cm)?

What is the x-component of the electric field at the position (x, y) = (0 cm, 5.2cm )?

What is the y-component of the electric field at the position (x, y) = (0 cm, 5.2cm )?

Here is what I solved before, please modify the figures as per your question. Please let me know if you have further questions. Ifthis helps then kindly rate 5-stars.

A -10nC charge is located at (x, y) = (1.1cm , 0 cm).

A) What is the x-component of the electric field at the position (x, y) = (5.2cm , 0 cm)?

B) What is the y-component of the electric field at the position (x, y) = (5.2cm , 0 cm)?

C) What is the x-component of the electric field at the position (x, y) = (?5.2cm, 0 cm)?

D) What is the y-component of the electric field at the position (x, y) = (?5.2cm, 0 cm)?

E) What is the x-component of the electric field at the position (x, y) = (0 cm, 5.2cm )?

F) What is the y-component of the electric field at the position (x, y) = (0 cm, 5.2cm )?

A) Ex = k*Q/rx^2

= 9*10^9*10*10^-9/(0.052-0.011)^2

= -5.354*10^4 N/c (towards -x axis)

B) Ey = 0

C) Ex = k*Q/rx^2

= 9*10^9*10*10^-9/(0.052+0.011)^2

= 2.267*10^4 N/c (towards +x axis)

D) Ey = 0

E) E = k*Q/rx^2

= 9*10^9*10*10^-9/(0.052^2+0.011^2)

= 1.664*10^4 N/c

theta = tan^-1(5.2/1.1) = 78.06 degrees

Ex = E*cos(78.06) = 0.344*10^4 N/c( towards +x axis)
B) Ey = -E*sin(78.06)

= -1.608*10^4 N/c
