Four identical plates of area A and separation d are connected as shown in diagram Each plates of capacitor are in horizontal plane and P Q and R are three points between plates P Q R 1 2 3 4 3mgd e E A Ife is in equilibrium between plates 2 and 3 then emf of battery is B Ratio of electric field at point P Q and R is 2 1 1 respectively C If plate 3 is shifted upward by d 2 ratio of potential difference between plate 1 between 2 and 3 will be 8 3 D ratio of electric field between plate 2 3 and 3 4 will be 4 1 after the shift
