The electric potential due to a point charge Q is completely in the radial direction (where point A is at a higher potential than point B at infinity and ‘r’ is the radial distance) is given as:

A. V = 4πQϵ0r
B. \(V = \frac{Q}{{4{\rm{\pi Q}}{_0}{\rm{r}}}}\)
C. \(V = \frac{{4{\rm{\pi Q}}{_0}{\rm{r}}}}{Q}\)
D. \(V = \frac{Q}{{4{\rm{\pi Q}}{_0}{{\rm{r}}^2}}}\)
Answer» C. \(V = \frac{{4{\rm{\pi Q}}{_0}{\rm{r}}}}{Q}\)
