have about them: Charge of X: 8.62? Two point-like charges are labeled X and Y. Here is the information that we have about them:
Charge of X: 8.62 µC
Mass of X: 2.83 g

Charge of Y: 1.78 µC
Mass of Y: 6.95 g
The charges are initially separated by a distance 0.65 m.

If the charges are released from rest, they repel from each other. After a long time has passed, the charges are at "infinity."
(a) What is the speed of X?

(b) What is the speed of Y?

I'm not sure if I'm doing this right but I used the Force=(k(Q1)(Q2))/r² which was .3588

Then I used F=ma or a=F/m Which I got an acceleration of 126.7999m/s² for X and 51.63m/s² for Y

I then thought of using v=vo + at but im not sure how this would work using infinity.
Any help would be great! Thanks.
