Aparticle of mass 10 g and charge 72 μc moves through a uniform magnetic field, in a region where the free-fall acceleration is −9.8j m/s2. the velocity of the particle is a constant 19i hat km/s, which is perpendicular to the magnetic field. what, then, is the magnetic field? (express your answer in vector form.)
