Aconductor carrying 14.7 amps of current is directed along the positive x-axis and perpendicular to a uniform magnetic field. a magnetic force per unit length of 0.125 n/m acts on the conductor in the negative y direction. what is the strength of the magnetic field at the place where the current is? 0.0001 t

Assume that two of the electrons at the negative terminal have attached themselves to a nearby neutral atom. there is now a negative ion with a charge -2e at this terminal. what are the electric potential and electric potential energy of the negative ion relative to the electron? the electric potential and the electric potential energy are both twice as much. the electric potential is twice as much and the electric potential energy is the same. the electric potential is the same and the electric potential energy is twice as much. the electric potential and the electric potential energy are both the same. the electric potential is the same and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron. the electric potential is twice as much and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron.
