Hello, it is given that the magnetic field b vector, so it is given that b vector in this case, this is b vector, and that is equal to 50 micro -teslas.
00:10
And it is directed into the plane of the paper or it is directed into the screen.
00:15
And the second one is the v vector, that is the velocity vector, that is 6 .12, multiplied 10 to the power 6 meter per second.
00:23
And it is directed towards the west.
00:25
So let us see the diagrammatic representation of the question here.
00:29
So let us consider this is the north direction opposite to it.
00:32
We have the south direction here.
00:34
And let us consider this is the west direction and this is the east direction like this.
00:38
So let us consider this is the x -axis over here and this is the y -axis over here.
00:42
So the velocity in this case is directed towards the west.
00:45
That is along the minus x -axis.
00:48
So we can otherwise write the velocity vector v vector and that is equal to 6 .2 in terms of direction as well...
