A disk of radius $\text{'}a\text{'}$ has a total charge $\text{'}Q\text{'}.$ Express the potential at point $\text{'}P\text{'},($i$)\text{'}a\text{'}$ unit away from the center of the disk; $($ii$)$ at the center of the disk. Also, find out at which point the potential will be minimum or maximum? Write the maximum and minimum potential for the disk if $R=10cm$ and $Q=10nC.$
