Two wires, each having a weight per unit length of 1.0 10-4 N/m, are strung parallel, one 0.10 m above the other. If the wires carry the same current, though in opposite directions, how great must the current in each wire be for the magnetic field of the lower conductor to balance the weight of the upper conductor?
Question 2
A stream of electrons passes through a velocity filter where the crossed magnetic and electric fields are 0.020 T and 5.00 104 V/m, respectively. Find the kinetic energy (in electron volts) of the electrons passing through the filter. 1 eV = 1.60 10-19 J
