A proton (mass m and charge +e) and an α - particle (mass 4m and charge +2e) are projected with the same kinetic energy at right angles to the uniform magnetic field. Which one of the following statements will be true
A
The α - particle will be bent in a circular path with a small radius that for the proton
B
The radius of the path of the 
particle will be greater than that of the proton
particle will be greater than that of the proton
C
The α - particle and the proton will be bent in a circular path with the same radius
D
The α - particle and the proton will go through the field in a straight line
Text Solution
Verified by ExpertsThe correct answer is:
C
