The magnetic force (Lorentz force) provides the centripetal force in this case, as Fc = mv 2 / r Since, here sin = 1 Then, the magnetic force: F = qvB Now, if the Lorentz magnetic force provides the centripetal force, therefore, these force must be equal as: qvB = mv 2 / r Solve the above expression for r as, r = mv / qB Radioactive particles are deflected in a magnetic field when they collide with something. If the field is in a vacuum, the magnetic field is the dominant factor determining the motion. A) The alpha particle will stop moving. Alpha particles are deflected by a magnetic field confirming that they must carry a charge. When alpha and beta particles move in magnetic fields they experience a deflecting force provided their motion is not parallel to the field. Which particles are not deflected by a magnetic field? This makes charges accelerate as they move in a potential gradient, just like a ball would accelerate if it rolled down a hill. Alpha rays (heavy, positively charged particles) are deflected slightly in one direction. a. This works out to be \[T = \dfrac{2\pi m}{qB} = \dfrac{2\pi (6.64 \times 10^{-27}kg)}{(3.2 \times 10^{-19}C)(0.050 \, T)} = 2.6 \times 10^{-6}s.\] However, for the given problem, the alpha-particle goes around a quarter of the circle, so the time it takes would be \[t = 0.25 \times 2.61 \times 10^{-6}s = 6.5 \times 10^{-7}s.\].
