Answer:
the radius of the circle is inversely proportional to the square root of magnetic field
Explanation:
If an electron is moving in circular orbit of radius "r" with speed "v"
so the time period of the motion of the charge is
now the current due to circulation of charge is
now magnetic field at the center of the circle is given as
plug in the value of current
So the radius of the circle is inversely proportional to the square root of magnetic field
