Answer:
2 J
Explanation:
A charged capacitor of capacitance with energy of 7.54 J, is connected in parallel with another capacitor
, so the charge is equally distributed between them.
(a) The energy stored in the capacitor before it being connected to the other capacitor is:
The energy stored in the electric field is the sum of the energies of the two capacitors:
since the charge equally distributed, =
=
. and since they are connected in parallel the potential difference on both of them is the same
:
hence,
