    Answer: V = 675000v

    Explanation:

    Electric potential V can be calculated by using the formula

    V = Kq/r

    Where

    V = electric potential

    q = charge = 15µC

    K = Coulomb constant = 9 × 10^9Nm^2C^-2

    r = 20 cm

    Substitute all the parameters into the formula

    V = (9×10^9 × 15×10^-6)/20×10^-2

    V = 135000/0.2

    V = 675000 volt
