There are three point charges in a system. The first is $5\mathrm{.}73$ muC and is located at $(0,-19\mathrm{.}5)$ m$.$ The second is $2\mathrm{.}63$ muC and is located at $(-24\mathrm{.}7,0)$ m$.$ The third is $9\mathrm{.}54$ muC and is located at $(-74\mathrm{.}8,-87\mathrm{.}4)$ m$.$ What is the potential $($in V$)$ at the origin due to these three charges?
