Hello.
00:01
So this is the figure that is given to us in the question.
00:04
Here we can see that the velocity v of the proton is perpendicular to the magnetic field b.
00:11
Now this velocity v is directed to the right and the magnetic field b acts into the plane of the screen or the plane of the paper.
00:22
Now we can see that both this v and b are perpendicular.
00:26
Now here we will be using fleming's left hand rule.
00:31
Fleming's left hand rule.
00:43
Now if we apply this rule, then we can say that the force on the particle or the proton will be acting in the upward direction.
00:53
Now since both v and b are perpendicular, what will happen? it will take a circular path.
01:01
Okay, so like this.
01:03
Now it will not complete this circular path.
01:06
Rather, what will happen? once it completes a semicircle, it will go out of this magnetic field in this direction.
01:17
Okay, that is parallel to this velocity.
01:20
Okay, so what will happen? first, it traces a semicircular path, semi -circular path, and moves out of the field, the magnetic field, anti -parallel to velocity.
01:58
Okay.
02:00
Anti -parallel velocity or in straight line in the direction from where it came...
