प्रश्न
How is the field directed if (i) the sheet is positively charged, (ii) negatively charged?
उत्तर
(1) `E =sigma/(2in_0)`
Direction of field will be away from the sheet if sheet is positively charged.
`(2) E= -sigma/(2in_0)`
Direction of field will be towards the sheet if sheet is negatively charged.
