Two particles of masses m_ a and m_ b and same charge are projected in a perpendicular magnetic field. They travel along circular paths of radius r_ a and r_ b such that r_ a >r_ b . Then which is true?

Options

  1. Am_ a v_ a >m_ b v_ b
  2. Bm_ a >m_ b and v_ a >v_ b
  3. Cm_ a =m_ b and v_ a >v_ b
  4. Dm_ b v_ b >m_ a v_ a

Correct answer

A. m_ a v_ a >m_ b v_ b

Step-by-step solution

Radius of circular path r_ a = m_ a v_ a q B and r_ b = m_ b v_ b q B According to question r_ a >r_ b m_ a v_ a q B > m_ b v_ b q B or m_ a v_ a >m_ b v_ b
