Electric charges and fields: Semicircular charge distributions

[Ujjwal28]

Homework Statement

If linear charge density is equal to 1micro coulomb per meter, then what is the electric field intensity at O?

Homework Equations

The Attempt at a Solution

The electric fields due to the two straight lines should cancel out.. But how to progress further? Please let me know...

But how to progress further?

Finding the fields due to the semi-circles, is it not?

 

[Ujjwal28]

Ok so... How is it done? Is there any formula or logic behind that?
