In this problem, i have a uniform electric field, which just means that the strength of the field is the same everywhere.
00:09
And i'm denoting that just by these mostly straight arrows.
00:15
And in this field, i place a proton and an electron.
00:20
I tried to show relative sizes.
00:22
Obviously, this is not the scale.
00:24
But the first thing we need to understand is that protons are much, much more massive than electrons.
00:28
Almost 2 ,000 times bigger, or more massive, i should say, than an electron.
00:35
But anyway, they both have the same charge.
00:38
The magnitude of charge is 1 .60 times 10 to the negative 19 coulums.
00:45
One is positive.
00:46
Obviously protons are positive.
00:47
Electrons are negative.
00:49
So if we place them in the field, using the equation, e equals f over q...
