The alpha particle has twice the electric charge of the beta particle but deflects less than the beta in a magnetic field because it
A)moves much slower.
B)moves much faster.
C)has much more inertia.
D)has much less inertia.

Question

Quizplus · Accepted Answer

The alpha particle has much more inertia due to its greater mass (it consists of two protons and two neutrons), which makes it less susceptible to deflection by a magnetic field compared to the lighter, negatively charged beta particle (an electron or positron).
