- The alpha particle will be bent in a circular path with a smaller radius than that of proton
- the radius of the path of the alpha - particle will be greater than that of proton
- the alpha particle and the proton will be bent in a circular path with the same radius
- the alpha - particle and the proton will go through the field in a straight path
Answer
(B) the radius of the path of the alpha - particle will be greater than that of proton
