Question

A charged particle of mass m and charge q is projected into a uniform magnetic field of induction b with speed v which is perpendicular to b the width of the magnetic field is d the impure imported to the particle by the field is

Answer 1

A small particle of mass m, charge q, and initial speed vo is projected into a uniform electric field E that is generated by a parallel plate capacitor of length a as shown in the figure below. The separation distance between the plates is unimportant however it is large enough such that the particle will not collide with the bottom plate. After passing through the field, it is deflected downward a vertical distance d and hits a collecting screen that is a horizontal distance b away. What is the particle’s charge to mass ratio (q/m) in terms of the given variables? Gravity does not need to be considered in this problem.
