The first part of the question is 3,100 V.

The second part of the question is 200 V.

Electric potential due to a point charge is given by

[tex]V = \frac{kQ}{r}[/tex]

here we know that

Q = charge

r = distance from the charge

[tex]V = \frac{9*10^9* 2.2* 10^{-6}}{6.3}[/tex]

[tex]V = 3142.8 Volts[/tex]

now again by the same equation

[tex]V = \frac{kQ}{r}[/tex]

[tex]V = \frac{9*10^9* 2.2* 10^{-6}}{99}[/tex]

[tex]V = 200 Volts[/tex]
