In this question we have given an oxygen ion that moves in an xy plane.
00:05
It is given that if the constant magnetic field is directed along the x -axis, then we have to find the magnitude of the magnetic force acting on the ion, and we have to find its acceleration.
00:17
So we have given that speed is 2 .7 into 10 to the power 3 meter per second.
00:30
As we know that charge of 1 oxygen ion is this is 1 .6 into 10 to the power minus 19 column.
00:48
And we have given that the magnetic field which is b is 3 into 10 to the power minus 5 tesla and it is directed along z axis.
01:08
And the particle is moving in x -y plane.
01:11
So the angle between the velocity and the magnetic field, that is theta, is 90 degree.
01:17
So as we know that magnetic force is given as that is f is equals to this is q into v cross b and that can be written as qv b sine theta.

So put the data in this equation...
