C.3 a) A square wire loop 8 cm on a side is perpendicular to a magnetic field of 5·10-3T. C.3 b) Calculate the magnetic flux through the loop? C.3 c) The field drops to 0 in 0.1s. Calculate the average emf which is induced in the loop during this period of time?

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.
