A -14 nC charge is located at (x, y) = (1.4 cm , 0 cm).

Part B

What is the y-component of the electric field at the position (x, y) = (5.9 cm , 0 cm)?

Express your answer to two significant figures and include the appropriate units.

Part D

What is the y-component of the electric field at the position (x, y) = (?5.9cm, 0 cm)?

Express your answer to two significant figures and include the appropriate units.

Part E

What is the x-component of the electric field at the position (x, y) = (0 cm, 5.9 cm )?

Express your answer to two significant figures and include the appropriate units.

Part F

What is the y-component of the electric field at the position (x, y) = (0 cm, 5.9 cm )?

Express your answer to two significant figures and include the appropriate units.

B)

E = k*q/r^2

= 9*10^9*14*10^-9/(0.014^2 + 0.059^2)

= 34267 N/c

angle made by E with +x axis

theta = tan^-1(5.9/1.4)

= 76.6 degrees

so, Ey = -E*sin(76.6)

= -34267*sin(76.6)

D) Ey = 3.3*10^4 N/C <<<<<<<<------------Answer

E) E = k*q/r^2

= 9*10^9*14*10^-9/(0.059 - 0.014)^2

= 6.2*10^4 N/c (towards -x axis)

so, Ex = -6.2*10^4 N/c <<<<<<<<------------Answer
