19 with charge qp = 1.60218 x 10 C and mass 27 mp = 1.6726 x 10 wire (opposite the current) with a constant velocity of 25200 m/s at a distance d above the wire. kg moves parallel to the The acceleration of gravity is 9.8 m/s. Determine this distance of d. You may ignore the magnetic field due to the Earth.

In a mass spectrometer, a beam of protons enters a magnetic field. Some protons make exactly a one-quarter circular arc of radius 0.50 m. a) If the field is always perpendicular to the proton's velocity, what is the field's magnitude if exiting protons have a kinetic energy of 10. keV? b) How long does it take the proton to complete the quarter circle? c) Find the net force (magnitude) on a proton while it is in the field.

A long straight wire carries a 1.5 A current. An electron moves parallel to the wire at speed 3.1 x 104 m/s. The distance between the electron and the wire is 8 cm. Calculate the magnitude of the magnetic force on the electron.(Give your answer in newtons but don't include the units.)

An electron moves at a velocity of 2.20 x 10^6 m/s in a direction perpendicular to a magnetic field of strength 1.89 T. How much force will the electron experience?
