Positive charges are uniformly distributed along the y-axis from y=0m to y=6m.......(blah blah blah)..... What is the resultant electric field at a point (x=3,y=3).

My question goes like this: will the y-components cancel out or you need to derive the formula for "a line charge with uniform distribution" formula?

PS: i can solve this problem question but got confuse whether to use the formula or derive another formula for this problem. thanks!

this is like a rod with uniformly distributed charges..

u have to find the electric field at point P

anonymous · Answer

that means y-components will cancel out? cuz based from the examples from other source of reference like:

|dw:1373302530548:dw|

the line marked with double dash means that the line(or should i say the component) is cancel out. im not so sure if this example can be apply to my question, the same rule of having a positive axis but still, the same position for electric field(which is located at the center regardless of the distance) of the line of charges with uniform distribution.

souvik · Answer

why they cancel out?

anonymous · Answer

forgot the explaination though but still, yah, 100% sure about this cancel thingy part. hehe
