Two large, thin metal plates are parallel and close to each other. On their inner faces, the plates have surface charge densities of opposite sign and of magnitude 17.0 xx 10^(-11)C//m^2. What is E (a) in the outer region of the first plate, (b) in the outer region of the second plate, and (c) between the plates? |
Answer» SOLUTION :`sigma=1.70 xx 10^(-11) CM^(-2)`  `a. E_(1)=(sigma)/(2epsi_(0)) -(sigma)/(2epsi_(0))=0` b. `E_(2)=(sigma)/(2epsi_(0)) -(sigma)/(2 epsi_(0))=0` `c. E_(3)=sigma/epsi_(0) =(1.7 xx 10^(-11))/(8.85 xx 10^(-12)) =1.9 NC^(-1)` |
