    4.8 \times 10^8 volts

    Explanation:

    The electric potential due to a point charge is given by

    V= \dfrac{1}{4 \pi \varepsilon_{0}} \dfrac{Q}{r}

    where Q = charge = 16 \times 10^{-9} C

    r = distance from a point = 3 \times 10^{-3} m

    \varepsilon_{0} = permitivity of free space

    = 8.85×10^-12 C^2/N-m^2

    Plugging in the numbers,

    V = \dfrac{1}{4 \pi (8.85 \times 10^{-12})} \dfrac{16 \times 10{-9}}{3 \times 10^{-3}}

    = 4.8 \times 10^8 volts
