I've got one more question for you guys. I am having a hard time understanding the problem, and thus can't solve it.
A long line of charge with charge per unit length lamda1 is located on the x-axis and another long line of charge with charge per unit length lamda2 is located on the y-axis with their centers crossing at the origin. In what direction is the electric field at point z=a on the positive z-axis if lamda1 and lamda2 are positive?
A. the positive z direction
B. the negative z direction
C. halfway between the x direction and the y direction
D. all directions are possible parallel to the xy plane
Any help understanding this problem would be great...and I'm sure I'll need some guidance in solving it. I really don't understand the "point z=a" portion of the question. Do I use the right hand rule here??
Thanks guys!
