An electron in a vaccuum is first accelerated by a voltage of 10,000 volts and then enters a region in which there is a uniform magnetic field of 0.6T at right angles to the direction of the electron's motion.
a) What is the force of the electron due to the magnetic field?
b) What will be the speed of the electron after is has been in the magnetic field for 10 seconds? Why?
Two automobiles, each of mass 900 kg, are moving at the same speed, 15 m/s, when they have an inelastic collision.(a) In what direction and at what velocity does the wreckage move if one car was driving north and one south? (b) In what direction a..
compute the force exerted by the man, the work done by the man on the piano, the work done by the friction force, the work done by the force of gravity, and the net work done on the piano.
