Question

a thin non conducting rod with a uniform distribution of positive charge Q is bend into a circle of radius R .The central perpendicular axis through the ring is z-axis with the origin at the centre of the ring . what is the magnitude of electric field due to the rod at
1) z=0
2) z=infinite
3) in term of R what positive value of z is the magnitude maximum?
4 ) if R=2cm and Q=4microC what is maximum magnitude?
