What is the electric field strength at the center of the triangle?

I have spent a lot of time on this problem and have not been able to get anywhere. Please help.

Try finding the field exerted by one rod at at time, and then add it all together vectorally.

Wouldnt two of them cancel out as they have the same charge?

This formula for electric field is due to a point charge at distance r from it, but in yout problem the charge is distributed over the rod or it is a linear charge distribution.ashkash said:the electric field, E=kq/r^2?

First find out the field due to charge on one rod by taking an infinitely small charge on a small element of the rod, have components along and perpendicular directions and then by integrating find the field due to the whole rod. Then the vector sum of the three fields will give the required field strenght.
