So here we're going to use a negative charge now.
00:04
We are again referring to figure 2250 from the textbook.
00:11
And for this entire thing, we're going to be using right -hand rule.
00:14
So for part a, b, c, d, e, f.
00:20
For part a, we know that their direction is down.
00:24
The magnetic field is outside the page.
00:27
And so the palm of your hand would be pointing to, the left or the west so we can say that magnetic force to the left or we can say west now for part b the direction of the velocity is up the direction of the magnetic field is to the right and so the palm points out of the page and so we can say that the magnetic force is out of the page now here for part c, we know that the direction of the velocity is to the right, the direction of the magnetic field is into the page.
01:17
And so we can then say that the magnetic force is to, rather we can say is down or we can say south.
01:40
Here for part d, the direction of the velocity is anti -paralleled to the magnetic field.
01:47
So here we have no force...
