An electron entering thomson’s e/m apparatus has an initial velocity (in horizontal direction only) of 4.0 x 10 6 m/s. in the lab there is a permanent horseshoe magnet of strength 12 mt, which you would like to use. (a) what electric field will you need in order to produce zero deflection of the electrons as they travel through the apparatus? (b) the length of nonzero e and b fields is 2.0 cm. when the magnetic field is turned off, but the same electric field remains, how far in the vertical direction will the electron beam be deflected over this length?

Aparticle of mass m is placed in a one-dimensional box of length l. the box is so small that the particle’s motion is relativistic, so that e p2/2m is not valid. (a) derive an expression for the energy levels of the particle using the relativistic energy–momentum relation and the quantization of momentum that derives from connement. (b) if the particle is an electron in a box of length l 1.00 1012 m, nd its lowest possible kinetic energy. by what percent is the nonrelativistic formula for the energy in error?

When can a theory be modified if a new type of technology allows for new observations that raise new questions? a-immediately, while the questions about the theory are being asked b-after new hypotheses related to the theory are tested in experiments c-only after the new observations disprove all parts of the theory d-while scientists begin to think about how the theory could improve
