Question

what is the solution to these questions? The potential difference between a pair of oppositely chargedparallel plates is 367 V. (a) If the spacing between the plates istripled without altering the charge onthe plates, what is the new potential difference between theplates?
V
(b) If the plate spacing is doubledwhile the potential difference between the plates is kept constant,what is the ratio of the final charge on one of the plates to theoriginal charge?

Explanation / Answer

    for a parallel plate capacitor     V = Q / C           = Q /o (A / d)           = Q d /o A (a)     tripling d while holding Q and A constanttriples V to 1101 V (b)     in this case     Qf = Qi / 2
