Match the Column I (potential) with Column II (value) for electric potential at different points `P_1, P_2, P_3 and P_4` as shown in the figure with respect to an electric dipole.Each points `P_1, P_2, P_3 and P_4` are equal distance r from mid-point `O` of dipole. Column I Column II A. `V_1` p. 0 B. `V_2` q. `p/(4sqrt2pi epsilon_0r^2)` C. `V_3` r. `(-p)/(4piepsilon_0r^2)` D. `V_4` s. `p/(4pi epsilon_0r^2)`

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 belowThe intensity of electric field at a point is `E=(sigma)/(epsilon_0)`where, `epsilon_0` = permittivity of free spaceThe ratio of E from right side of plate B at distances 2 cm and 4 cm, respectively
