## Homework Statement

This is a problem I was thinking about which I haven't come across in my course.

Two particles with mass, m, and a positive charge, q, are separated by a distance r

_{0}. One particle is unable to move while the other is released and is repelled. Find an equation for the motion of the particle.

## Homework Equations

F=q

^{2}/cr

^{2}

a=F/m

## The Attempt at a Solution

The problem I have in working out the acceleration at any time here is that r is a time dependent variable.

Although this seems like a pretty important thing to know how to calculate I end up going around in circles with the maths.
