In the figure shown capacitors `A` and `B` of capacitance `C` are in steady state. A dielectric slab of dielectric constant `K=2` and dimensions equal to the inner dimensions of the capcitors is inserted in the space between the plate of the capacitor `B`. In steady state choose the correct options.

Options

A. In the proces of inserting the dielectric, energy of the battery increases by an amount of `(CE^(2))/6`
B. In the process of inserting the dieelectric, energy in the capacitor `A` increases by an amount of `(7CE^(2))/72`
C. Charge on each capacitor will increase by `(CE)/6`.
D. In the process of inserting the dielectric, energy of the battery decreases by an amount of `(CE^(2))/6`.

Answer

B, C, D
