Infinity is not a point in time.
Pick some value for time and add one.

but the question stands that way. it means, at the end, when the
particles are almost collinear to A, the distance b/w them is _______.
one may imagine q is on A-p, position A and particle p.

one idea that i have is that from the frame of reference of p, q is
moving in a straight line towards itself....but even thn how to
proceed?

thanks for trying.
