Explanation:
Given that,
Singly charged uranium-238 ions are accelerated through a potential difference of 2.20 kV and enter a uniform magnetic field of 1.90 T directed perpendicular to their velocities.
We need to find the radius of their circular path. The formula for the radius of path is given by :
m is mass of Singly charged uranium-238 ion,
q is charge
So,
So, the radius of their circular path is equal to 0.0548 m.
