Given:

A thin ring of radius R has a charge Q non-uniformly distributed on it.

To find:

Electrostatic Potential at centre of ring?

Calculation:

Let's consider an elemental part of ring containing charge dq and total charge of ring be Q.

So, potential due to elemental charge will be:

 \: dV =  \dfrac{k(dq)}{r}

Now, integrating on both sides:

  \displaystyle \implies \int dV =   \int\dfrac{k(dq)}{r}

  \displaystyle \implies \int dV =   \dfrac{k}{r}  \int \: dq

  \displaystyle \implies V =   \dfrac{kQ}{r}

  \displaystyle \implies V =   \dfrac{Q}{4\pi  \epsilon_{0}r}

Hope It Helps
