Three identical metal plates with large surface areas are kept parallel to each other.The leftmost plate is given a charge Q, the rightmost is given a charge -2Q & the middle one remains neutral.Find the charge appearing on the outer surface of the rightmost plate. { plzz let me know how to you take the sign meaning + or - for the electric field due to each surface of the plate}
Let's say three plates charges Q1,Q2,Q3 We find equations by assuming electric field in the conductor zero. Charges are conserved on each plate. Thanks & RegardsArun KumarIIT DelhiAskiitians Faculty
