Question

o do- ve lom 60° ds

URGENT!!!
The image is of two rods, each forming an arc, and one bigger than the other.

1) Calculate the net charge on each rod.
2) Find the magnitude and direction of the electric field at the origin.
3) Find the electric potential at the origin.

Notes: apparently the equation V= K* Q/2R should be used for one arc and V= K*Q/R should be used for the other. (?)
Should the angle be in radians in this problem?
Should 2 rings be used as Gaussian surfaces for each arc? (Please answer)

Please, show clear work and don't skip steps! Explain equations and steps used here and there if possible. I really want to understand this. Thank you in advance to whomever answers!
