A proton (charge le, mass mp) and an alpha particle (charge 2e, mass 4mp) in a mass spectrometer are accelerated from rest through a velocity selector that has an electric field E 103 V/m and magnetic field B- 2.5T. Each of the particles enters a uniform magnetic field B-2.5T, with its velocity in a direction perpendicular to B. The proton moves in a circular path of radius rp. and the alpha particle in a circular path ra. Calculate the distance...

An alpha particle is a nucleus of helium. It has twice the charge and four times the mass of the proton. When they were very far away from each other, but headed toward directly each other, a proton and an alpha particle each had an initial speed of 8.2×10−3 c, where c is the speed of light. What is their distance of closest approach? There are two conserved quantities. Make use of both of them. (c = 3.00 × 108...
A proton and an alpha particle (charge = 2e, mass = 6.64 ✕ 10−27 kg) are initially at rest, separated by 4.97 ✕ 10−15 m. Find the speeds of the proton and alpha particle, respectively, at infinity?
The figure below shows the positions of two alpha particles (each alpha particle has a charge +2e and an electron. a) Draw a clear and neat free-body diagram for either sphere at equilibrium. b) Determine the magnitude and direction of the resultant force on the electron. (Hint: Choose the +x-axis along the line from the electron to the right-hand particle.) c) Determine the acceleration of the electron due to the net force acting on it. The mass of the...
