Capacitor question

2019 · 9 Apr · Shift 2 · Q46

JEE MainPhysicsCapacitorMCQ+4 / −1
The parallel combination of two air filled parallel plate capacitors of capacitance C and nC is connected to a battery of voltage, V. When the capacitors are fully charged, the battery is removed and after that a dielectric material of dielectric constant K is placed between the two plates of the first capacitor. The new potential difference of the combined system is :-
  1. A
    V
  2. B
    VK+n{V \over {K + n}}K+nV​
  3. C
    (n+1)VK+n{{(n+1)V} \over {K + n}}K+n(n+1)V​
  4. D
    nVK+n{{nV} \over {K + n}}K+nnV​
