MHT CET 2024 Physics question
A charged particle of charge 'q' is accelerated by a potential difference 'V' enters a region of uniform magnetic field 'B' at right angles to the direction of field. The charged particle completes semicircle of radius 'r' inside magnetic field. The mass of the charged particle is
Answer: (A)
Solution
Acceleration through gives , so . In the magnetic field the circular path has , so . Solving for the mass, $m =
