Physics · Magnetic Fields
Two charged particles having specific charges (charge-to-mass ratio) in the ratio 2 : 1 and masses in the ratio 1 : 4 move with the same kinetic energy. They enter a uniform magnetic field at right angles to the direction of the field. The ratio of the radii of the circular paths in which the particles move under the influence of the magnetic field is:
- 18 : 1
- 24 : 1
- 31 : 1✓
- 42 : 1
Correct answer
1 : 1
