Express your answer in terms of the given quantities.<br />
ANSWER:<br />
E y =<br />
Part C<br />
Calculate the z-component of the electric field.<br />
Express your answer in terms of the given quantities.<br />
ANSWER:<br />
E z = 0<br />
Part D<br />
At which point is the electric field equal to zero?<br />
ANSWER:<br />
x = 0 , y = 0 , z = 0<br />
x = −C/A , y = 0 , z = −2BC/A 2<br />
x = −C/A , y = −2BC/<br />
, z = C/A<br />
