Modeling the motion of electric charges

Hello

I am calculating the motion of 2 electric charges Which are initially at rest and are 1 meter apart. The force between these two charges is the coulomb type And other forces are ignored.I want to find the speed and location of electric charges at any time. can you help me?How should I write this code? I want to implement this algorithm:

1-Calculate the force at each distance assuming that the charges are 1 and 2 coulomb

2-Calculate the accelerations at any distance assuming that the mass of charges are 1 and 2 kg

3-Calculation of speed by acceleration

4-and Finally calculation of location or distance by speed

Thank you for your attention
