An alpha particle (a he nucleus, containing two protons and two neutrons and having a mass of 6.6. an alpha particle (a he nucleus, containing two protons and two neutrons and having a mass of 6.64×10−27 kg ) traveling horizontally at 36.6 km/s enters a uniform, vertical, 1.10 t magnetic field.
(a)- what is the diameter of the path followed by this alpha particle? express your answer in millimeters to three significant figures.
(b)- what effect does the magnetic field have on the speed of the particle?
(c)- what is the magnitude of the acceleration of the alpha particle while it is in the magnetic field? express your answer in meters per second to three significant figures.
(d)- what is the direction of the acceleration of the alpha particle while it is in the magnetic field?
(e)- explain why the speed of the particle does not change even though an unbalanced external force acts on it.
