Question
Chapter 39, Problem 42A
To determine
The reason for less deflection of the alpha particle than beta particle in the magnetic field.
Expert Solution & Answer
Explanation of Solution
Introduction:
The deflection of the particle depends on the mass and speed of the particle.
The alpha particle contains the two protons and beta particles contain one electron. The mass of the proton is more than the mass of electron. The speed of the electron is very high than the speed of the proton.
The electrons pass from magnetic field with very high speed than the speed of proton. The magnetic force on beta particles is less than the magnetic force on alpha particle So, the alpha particles deflect more than the beta particle in the magnetic field.
Conclusion:
Thus, the alpha particle deflects more than the beta particles in magnetic field because the alpha particle is heavier and slower than the beta particles.

Set the wavelength to the (default) 0.55 microns and a single on-axis field point at infinite object distance. Set the image distance to 200 mm. Make the first surface the stop insure that the lens is fully filled (that is, that the entrance beam has a radius of 10 mm). Use the lens-maker's equation to calculate initial glass curvatures assuming you want a symmetric, bi-convex lens with an effective focal length of 200 mm. Get this working and examine the RMS spot size using the "Text" tab of the Spot Diagram analysis tab (OpticStudio) or the Spd command of the text widnow (OSLO). You should find the lens is far from diffraction limited, with a spot size of more than 100 microns. Now let's optimize this lens. In OpticStudio, create a default merit function optimizing on spot size.Then insert one extra line at the top of the merit function. Assign the…arrow_forward
