A -15 nC charge is located at ( x , y ) = (1.4 cm , 0 cm). Part D What is the y

Question

A -15 nC charge is located at (x, y) = (1.4 cm , 0 cm).

Part D

What is the y-component of the electric field at the position (x, y) = (4.1cm, 0 cm)?

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

Ey= ??

Part E

What is the x-component of the electric field at the position (x, y) = (0 cm, 4.1 cm )?

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

Ex= ??

Part F

What is the y-component of the electric field at the position (x, y) = (0 cm, 4.1 cm )?

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

Ey= ??

Explanation / Answer

PartD] Ey = 0, because of symmetry, it will have n y component.

partE] Ex = kq/r^2 cos theta

= 9e9*15e-9/(0.041^2 +0.014^2)*1.4/sqrt(0.041^2 +0.014^2)

= 2.3*10^4 N/C

partF) Ey = kq/r^2 sin theta

= -9e9*15e-9/(0.041^2 +0.014^2)*0.041/sqrt(0.041^2 +0.014^2)

= -6.8*10^4 N/C
