A cube that is

0.43m

on an edge is oriented with one corner at the origin and three edges along the axes of a Cartesian coordinate system. The electric field in this region of space is parallel to the

z

axis. The electric field at the top of the cube (at

z=0.43m

is

vec(E)=(1240(N)/(C))widehat(k)

. The electric field at the bottom of the cube (at

z=0m

) is

vec(E)=(620(N)/(C))widehat(k)

.

A cube that is 0.43m on an edge is oriented with one corner at the origin and three edges along the axes of a Cartesian coordinate system. The electric field in this region of space is parallel to the z axis. The electric field at the top of the cube (at z=0.43m) is E=(1240N/C)k. The electric field at the bottom of the cube (at z=0m) is E=(620N/C)k
