Five positive charges each having charge $\displaystyle q$ are placed at the vertices of a pentagon as shown in the figure. The electric potential $\displaystyle (V)$ and the electric field $\displaystyle (\vec{E})$ at the center $\displaystyle O$ of the pentagon due to these five positive charges are :
