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?

Asheet of steel 1.5 mm thick has nitrogen atmospheres on both sides at 1200oc and is permitted to achieve a steady-state diffusion condition. the diffusion coefficient for nitrogen in steel at this temperature is 6 x 10- 11 m2 /s, and the diffusion flux is found to be 1.2 x 10-7 kg/m2 -s. also, it is known that the concentration of nitrogen in the steel at the high-pressure surface is 4 kg/m3 . how far into the sheet from this high-pressure side will the concentration be 2.0 kg/m3 ? assume a linear concentration profile.

On a frictionless air track, a blue glider with mass 0.200 kg is moving to the right with a speed of 8.00 m/s. it strikes a red glider that has mass 0.600 kg and that is initially at rest. after the collision, the blue glider is moving to the left with a speed of 3.00 m/s.(a) what are the magnitude and direction of the velocity of the red glider after the collision? (b) is this collision elastic?
