Step-by-step explanation:

The electric potential can be calculated as:


V=k(Q)/(r)

Where k is 9 x 10⁹ N m²/C², r is the distance and Q is the charge.

So, replacing each value, we get:


-500=(9*10^9)(-5.35*10^(-6))/(r)

Then, solving for r:


\begin{gathered} -500=(-48.15*10^3)/(r) \\ 500r=48.15*10^3 \\ r=(48.15*10^3)/(500) \\ r=96.3\text{ m} \end{gathered}

Therefore, the distance is 96.3 m
