Write $SI$ and $CGS$ unit of gravitational potential.

(N/A) Gravitational potential $(V)$ at a point is defined as the work done per unit mass in bringing a test mass from infinity to that point.
Mathematically,$V = \frac{W}{m}$.
In $SI$ units,work is measured in Joules $(J)$ and mass in kilograms $(kg)$. Therefore,the $SI$ unit is $J/kg$ or $m^2/s^2$.
In $CGS$ units,work is measured in ergs $(erg)$ and mass in grams $(g)$. Therefore,the $CGS$ unit is $erg/g$ or $cm^2/s^2$.
