## Homework Statement

The electric potential at a distance of 20.5 cm from a very small charged sphere is 33.0 V, with the potential taken to be zero at an infinite distance from the sphere.

If the sphere is treated as a point charge, what is its charge?

## Homework Equations

[tex] V = \frac {U} {q_{0}} == \frac {1} {4*pi*(8.85*10^{-12})}*\frac {q} {r} [/tex]

## The Attempt at a Solution

How do you convert 33.0V to the correct units of Q or is it equliv?

[tex] \frac {1} {4*pi*(8.85*10^{-12})}*\frac {33.0} {0.255} [/tex] ??
