Answer:
The final energy will be halved of the original energy.
Explanation:
As we know that the capacitance,
C = εA/d
C = capacitance
A = area of plate
d = distance or separation between the plates
ε = permitivity of dielectric material
As you can see from the formula that the capacitance ( ability of the capacitor to store charge) is inversaly proportional to the separation of the plates. If all the other factors kept constant then increasing the distance between the plates will decrease the ability of the capacitor to store energy. So we can say that by doubling the separation, the capacitance or energy stored will become half.
The answer is b. because they move freely
