The second figure in the book shows the particles' deflection in a magnetic field, again with no explanation, leaving me to fumble around with my own ideas Now, I guess the reason why the alpha particle didn't deflect quite as much here is due to its weight, but my reasoning breaks down for the beta particle shouldn't it not have deflected as drastically due to its immense velocity? But despite the greater speed, the larger mass makes the alpha particle have a lot more momentum than the beta particle.
