Two thin infinite parallel sheets have uniform surface charge densities of `+sigma` and `-sigma`. Electric field is the space between the two sheets is :

Text Solution

Verified by Experts

Electric field Inside the sheets at point `P_(1)`
`EP_(1)=E_(1)+E_(2)=(sigma)/(2 in_(0))+(sigma)/(2 in_(0))=(sigma)/(in_(0))`
Electric field outside the sheets at point `P_(2)`
`EP_(2)=E_(1)-E_(2)=(sigma)/(2 in_(0))-(sigma)/(2 in_(0))=0`
