Charge between Parallel Plates
Surface charge density is defined as the charge per unit surface area of surface charge distribution, `i.e. sigma = (dq)/(dS)`
Two large, thin metal plates are parallel and close to each other. On their inner faces, the plates have surface charge densities of opposite signs having magnitude of `17.0 xx 10^(-22) Cm^(-2)` as shown below
The intensity of electric field at a point is `E=(sigma)/(epsilon_0)`
where, `epsilon_0` = permittivity of free space
The ratio of E from right side of plate B at distances 2 cm and 4 cm, respectively is
Options:
(a) 1 :2
(b) 2 :1
(c) 1 :1
(d) `1 :sqrt2`
