Answer:
Explanation:
Radius of the path of electron which is moving perpendicular to magnetic field is defined as,
Here, m is the mass of electron, v is the velocity of electron, q is the charge on electron, and B is the magnetic field.
Given that, the velocity of electron is, .
And the magnetic field is .
And the mass of electron is,
And the charge on electron is,
Put all these values in radius equation,
Therefore, the path radius of a moving electron is
