Problem 4 Consider a one-dimensional charged harmonic oscillator. Let the coordinate be, charge be q, mass be m, and the frequency of the oscillator be u. (a) 79 rat t =-oo, the oscillator is in the ground state 10). A uniform electric field E along x axis is applied betweentoo andtoo with the time dependence of E being...
A Rail Gun uses electromagnetic forces to accelerate a projectile to very high velocities. The basic mechanism of acceleration is relatively simple and can be illustrated in the following example. A metal rod of mass m and electrical resistance R rests on parallel horizontal rails (that have negligible electric resistance), which are a distance L apart. The rails are also connected...
A rail gun uses electromagnetic forces to accelerate a projectileto very high velocities. The basic mechanism of acceleration isrelatively simple and can be illustrated in the following example.A metal rod of mass 50.0 and electricalresistance 0.400 rests on parallel horizontalrails that have negligible electric resistance. The rails are adistance = 6.00 apart. The rails are alsoconnected to a voltage source...
Scientists are working on a new technique to kill cancer cells by zapping them with ultrahigh-energy (in the range of 1012 W) pulses of electromagnetic waves that last for an extremely short time (a few nanoseconds). These short pulses scramble the interior of a cell without causing it to explode, as long pulses would do. We can model a typical...
Charging by Induction CBI-1 Atoms in a non-conductor in the absence of any non-conductor external charges (or electric fields) are symmetric, as shown in the figure to the right. If a positively charged rod is brought near the non-conductor, the nuclei + charges) can't move, but the electrons can shift within each atom. Draw the electrons in the atoms in...
Two very long concentric conducting cylindrical shells are arranged as seen below. The inner shell has a radius a, and the outer shell a radius b. Each shell has a length L. A charge of -Q is spread over the inner shell and a charge of +Q resides on the outer shell. Ignore fringe fields (e.g. assume each cylinder is...
For questions I -6, either indicate the correct aimer in the blank or select the answer which most correctly answers the question. These questions do not require calculations and you do t hove to show your work. Please clearly indicate your answers !! In the equation the symbol stands for Electric Field Electric Force Electric Flux Electric Energy Which two...
One observes electrons curve right in the presence of an applied magnetic field. If one were to shoot protons instead, which direction would they curve? Possible Answers: A)The protons curve right, they produce a magnetic field. B) The protons curve right, their relativistic mass increases. C)The protons curve left, because they are positively charged.
answer is NOT 6.7328e-20
B) is into the page
One common type of cosmic ray is a proton traveling at close to the speed of light. If the proton is traveling downward, at speed of 2.63 times 10^7 m/s, What are the magnitude and direction of the magnetic field at point A?
