## Homework Statement

Two charged beads, Q1 and Q2, are placed on a long frictionless (insulating) rod. Initially they are very far apart; the bead Q2 is glued in place and does not move. Both beads have mass 10g and carry charge 2uC. Q1 is set in motion at a velocity v= 10 m/s towards Q2.

A) How close does Q1 get to Q2 before reversing its direction of motion?

B) What is the maximum force exerted on charge Q1?

## Homework Equations

This is kinda how the diagram that goes with it looks like:

<-------*-----------------------------------------*-------------------->

In which the first asterix is Q1 -->

and the second asterix is the fixed Q2

## The Attempt at a Solution

I don't know where to start. Don't i need to know how far apart they are in order to find out how close Q1 will get? Ugh.
