Two particles, with identical positive charges and a separation of 2.60 x 10^-2 m, are released from rest. Immediately after the release, particle 1 has an acceleration a1 whose magnitude is 4.60 x 10^3 m/s^2, while particle 2 has an acceleration a 2 whose magnitude is 8.50 x 10^3 m/s^2. Particle 1 has a mass of 6.00 x 10^-6 kg. What is the charge on each particle and what is the mass of particle 2?

Forces are equal.

F1=F2
a1*m1=a1*m2

solve for m2.

Now, you know f=kqq/r^2=ma
solve for q
