Select the statements below that are true. Select all that apply. The earth’s magnetic field has no effect on the electron rays coming from the sun. If a bar magnet is cut in half two magnets with opposite poles will be created. An example of the Biot-Savart law is the effect of the earth’s magnetic field on the electron rays coming from the sun. The north pole of a magnet will be attracted to the north pole of the earth. Magnetic fields point from the south pole to the north pole of a magnet.

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.
