(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Right, the problem is of course to sketch a graph of velocity against distance in an electric field.

the second part, drawing the grapgh with an electric field opposing the motion of the electron.

3. The attempt at a solution

Right, assume we have an electron. We know that the electrical field strengh/intensity would be uniform.

So we know that Electric field strength=force/charge. Since the electric field strength is constant, an electron will experience constant force throught the electric field.

So since, f=ma, the acceleration is constant.

So the graph of velocity against distance will be a straight line.

Please explain to me whether my reasoning is correct.

Now, the second part.

The electrical field lines are opposing the motion of the electron.

The electron will experience a constant opposing force. But it takes time for these two forces to balance. (the motion of the electron) against the opposing force because of the electric field.

So now the graph should look similar to a terminal velocity graph or underoot x graph.
