At which point is the electric field equal to zero? x=0,y=0,z=0 x=?C/A,y=0,z=?2BC/A2 x=?C/A,y=?2BC/A2,z=C/A

Explanation / Answer

Calculate the -component of the electric field

Ex= -Ay+2Bx

Calculate the -component of the electric field.

Ey= -Ax-C

Calculate the -component of the electric field

Ex=0

At which point is the electric field equal to zero?

X=-C/A ,y=-2BC/A^@ , Z= C/
