Explanation:
When a capacitor is charged by a battery, it stores energy in the form of electric field between its plates. The energy stored in the capacitor is given by:
E = 1/2 CV²
Where E is the energy stored, C is the capacitance of the capacitor and V is the voltage across it.
When another identical uncharged capacitor is connected in parallel, the total capacitance of the system increases but the voltage across each capacitor remains the same. The total energy stored in the system is given by:
E' = 1/2 C'V²
Where C' is the total capacitance of the system, which is equal to 2C in this case, and V is the voltage across each capacitor.
Thus, we can see that the total energy stored in the system has increased by a factor of 2. However, the question asks for the change in electrostatic energy, which is the energy stored in the electric field between the plates of the capacitor. Since the voltage across each capacitor remains the same, the electrostatic energy stored in each capacitor remains the same. Therefore, the total electrostatic energy of the system decreases by a factor of 2.
Thus, the correct answer is option 'A'.
