Expert Answer
Electric field E at distance r from infinite line charge that has linera charge density λ is given as
 
begin mathsize 14px style E space equals space fraction numerator lambda over denominator 2 pi space r space epsilon subscript o end fraction end style
begin mathsize 14px style lambda space equals space left parenthesis space 2 space pi space r space epsilon subscript o space right parenthesis space E end style
λ = ( 2 π ) × 2 × 10-2 × 8.854 × 10-12 × 9 × 109 =  1 C/m
