A beam consisting of protons and electrons moving at the same speed goes through athin region in which there is a magnetic field perpendicular to the beam. Protons and the electrons

If proton and electron have same de-Broglie wavelength then….

Which type of electric force acts between the proton and the electron?

A proton and a deuteron having the same kinetic energies enter a region of uniform magnetic field perpendicularly, Deuteron's mass is twice that of proton. Calculate the ratio of the radii of their circular paths.

A magnetic field set up using Helmholtz coils (described in Exercise 4.16) is uniform in a small region and has a magnitude of 0.75 T. In the same region, a uniform electrostatic field is maintained in a direction normal to the common axis of the coils. A narrow beam of (single species) charged particles all accelerated through 15 kV enters this region in a direction perpendicular to both the axis of the coils and the electrostatic field. If the beam remains undeflected when the electrostatic field is 9.0xx10^(-5)Vm^(-1) , make a simple guess as to what the beam contains. Why is the answer not unique ?

If a proton and an electron are confined to the same region.then uncertainty in momentum ……..

An electron having 182 eV kinetic energy is moving on a circular path in a magnetic field of 10^(-4)T . The speed of the electron is ......

A monoenergetic (18 keV) electron beam initially in the horizontal direction is subjected to a horizontal magnetic field of 0.04 G normal to the initial direction. Estimate the up or down deflection of the beam over a distance of 30 cm (m_(e) = 9.11 xx 10^(-31) kg) . [Note : Data in this exercise are so chosen that the answer will give you an idea of the effect of earth's magnetic field on the motion of the electron beam from the electron gun to the screen in a TV set.)
