The speed of the particle when it enters the magnetic-field region is 120,000 m/s.

Speed of the particle

Magnetic force on the particle is given as;

F = qvB

where;

  • q is magnitude of the charge
  • v is speed of the particle
  • B is magnetic field strength

From Newton's second law, force on an object is given as;

F = ma

where;

  • m is mass of the particle
  • a is acceleration

ma = qvB

v = ma/qB

v = (3 x 10⁻² x 12)/(3 x 10⁻⁶ x 1)

v = 120,000 m/s

Thus, the speed of the particle when it enters the magnetic-field region is 120,000 m/s.
