The speed of the particle when it enters the magnetic-field region is 120,000 m/s.
<h3>
Speed of the particle</h3>
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.
