Five plates with same area are placed as in figure. Distance between any 2 consecutive plates is d. Find equivalent capacitance(ab). (Note-Answer is given as 5C/3, in terms of C so I suppose C is capacitance of a +ve and -ve plate separated by d). The lower letter is A, it is marked positive and upper letter is B marked negative.
The Attempt at a Solution
numbering 1 to 5 from top to bottom. I can see 1 capacitor due to negative 2 and positive 3 and none else since 1 and 4 are uncharged so answer should be C...unless charges get induced. In that case there are 4 capacitors and answer should be 4C. I'd be grateful for some help.
