. A proton a deuteron and an alpha


particle are projected perpendicular to the direction of a uniform magnetic field with same kinetic energy. The ratio of the radii of the circular paths described by them is

A: √(2) :1:√(2)

B: 1:√(2) :1

C: √(2) :√(2) :1

D: √(2) :1:1

 

Best Answer

Explanation:

When particle is moving perpendicular to a magnetic field, then it moves in circular path of radius.

particles is same

 

Final Answer:

The ratio of the radii of the circular paths described by them is given by option B. (1:√2:1)
