$(17-24)$ Two identical $+9\mathrm{.}5C$ point charges are initially $5\mathrm{.}3$ cm from each other. If they are released at the same instant from rest, how fast will each be moving when they are very far away from each other flet V$=0$ and $x=?$ Assume they have identical masses of $1\mathrm{.}0$ mg $.$
