1.	An unchanged capacitor with a solid dielectric is connected to a similar air capacitor charged to a potential of `V_(0).`. If the common potential after sharing of charges becomes V, then the dielectric constant of the dielectric must beA. `(V_(0)-V)/V`B. `(V_(0)+V)/V`C. `V_(0)/V`D. `V_(0)/(2V)`
Answer» Correct Answer - A `V=(C_(1)V_(1)+C_(2)V_(2))/(C_(1)+C_(2))` `=(CKxx0+CV_(0))/(CK+C)=(CV_(0))/(C(K+1))=V_(0)/(K+1)` `K=(V_(0)-V)/V`
