What is the direction of electric force in point A for a charged triangle ABC?

[sma]

Consider triangle ABC,the continues charges distribution lies on the side of BC with the linear charge density such as m,prove that the direction of electric force in the point A lies on the bisector of the viewing angle BAC

 

[cartonn30gel]

try to think which components of the electric force cancel out at A

I don't Underestand

 

[chroot]

Look at the force due to the charge on the left half of BC, and due to the charge on the right half of BC. What can you say about the magnitude and direction of those forces in relation to each other?
