Capacitors and Capacitance. I need lots of help with this question. Can someone be please help me with this problem? Thank you.

Capacitor paradox Two capacitors with the same capacitance C and charge Q arc placed next to each other, as shown in Fig. 3.39. The two positive plates arc then connected by a wire. Will charge flow in the wire? Consider two possible reasonings: Before the plates arc connected, the potential differences of the two capacitors arc the same (because Q and C arc the same). So the potentials of the two positive plates arc equal. There fore. no charge will flow in the wire when the plates are connected. Number the plates I through 4. from left to right. Before the plates are connected. there is zero electric field in the region between the capacitors, so plate 3 must be at the same potential as plate 2. But plate 2 is at a lower potential than plate I. Therefore, plate 3 is at a lower potential than plate I. so charge will flow in the wire when the plates are connected. Which reasoning is correct, and what is wrong with the wrong reasoning?

Explanation / Answer

reasons 1 is coorect and reason 2 is wrong

there exists some potnetial difference betweed the plates goverend byn the equation, V = (E-2-E1) d

and charge Q = CV

---------------------------------------------------

reason B is wrong such that between the plate EF is not zero. it is constant and is givne nby E = sigma/2eo
