Electric field is vB
And induced charges on metallic sheet create electric field sigma/epsilon equate it @Rishabh_Singh8
@Siddhant_Mudholkar if it's a conducting sheet shouldn't the field be sigma/2.epsilon.on each face?
But if I do that it's not matching
Yes in sheet it's sigma/2epsilon
Then why isn't the 2 showing up in the answer? @Siddhant_Mudholkar
But that electric field is for outside
