    Energy stored in the capacitor = 2.2 x 10⁻¹⁰ J

    Explanation:

    The energy stored in the capacitor is given by

    E = 1/2 q V

    E = energy stored

    q = charge = 7.6 x 10⁻¹¹ C

    V = potential difference=5.8 V

    so energy stored = E = 1/2 (7.6 x 10⁻¹¹) (5.8)

    Energy stored = 2.2 x 10⁻¹⁰ J
