Answer:
V = 360 kV
Step-by-step explanation:
Given that,
Charge, q = -2µC
We need to find the electric potential difference of 5cm from a point charge.
We know that the formula for the electric potential is given by :
![V=(kq)/(r)\\\\V=(9* 10^9* 2* 10^(-6))/(0.05)\\\\V=360000\ V](https://img.qammunity.org/2022/formulas/physics/high-school/wyod7btqlk18y0cwvqo9wdtf1sqtrfrfl1.png)
or
![V=360\ kV](https://img.qammunity.org/2022/formulas/physics/high-school/1bsqlv73yzyy7qdyiz2j76w24x83kzljsd.png)
So, the electric potential difference is 360 kV.
