An electron moves in a uniform magnetic field of 0.20 T, at 5.0 x 105 m/s. The magnetic force on it is a) 1.6 x 10-14 N b) 1.6 x 10-14 N [perpendicular to the velocity]
c) 1.6 x 10-14 N [perpendicular to the field] d) not enough information given

A200-n force is applied to the foot-operated air pump. the return spring s exerts a 2.6-n·m moment on member oba for this position. determine the corresponding compression force c in the cylinder bd. if the diameter of the piston in the cylinder is 40 mm, estimate the air pressure generated for these conditions. state any assumptions. enter a positive number for the compression force c.
