Expert Answer:

(1) Field due to long charged rod
Equation for Electric field intensity due to Long rod:-    begin mathsize 12px style E left parenthesis d right parenthesis space equals space fraction numerator 1 over denominator 4 pi epsilon subscript 0 end fraction space fraction numerator lambda L over denominator d square root of d squared plus begin display style L squared over 4 end style end root end fraction end style
 
(2) Spherical Shell
For spherical shell when the distance is less than radius :- begin mathsize 12px style E left parenthesis r right parenthesis space equals space fraction numerator 1 over denominator 4 pi epsilon subscript 0 end fraction fraction numerator Q r over denominator R cubed end fraction end style
When the distance is greater than radius begin mathsize 12px style E left parenthesis r right parenthesis space equals space fraction numerator 1 over denominator 4 pi epsilon subscript 0 end fraction Q over r squared end style
Q is the charge on shell
