An electron emitted by a surface made of Gold is observed with an energy of 9 eV. What was the energy of the electron in the Gold in eV? Number The work function of Gold is 5.1 eV. Consider an area of 0.38 square meters, the normal to the area is at angle 17 degrees to a magnetic field of 1 Tesla. What is the magnetic flux through the area in units of T m2- Number The compaarion is done to 1% accuracy. A square loop of wire is rotated at frequency 95 Hz in a magnetic field of 5 T. The length ot one side at the square is 0.26 m. What is the amplitude of the voltage? Number The answer should be accurate to 1% and have units of V. .._...........g ......_ _-.-_.__ An unknown ion is accelerated by a potential of 7,990 V. A magnetic field of magnitude 9 T bends the beam with a radius of 0.26 m. What is the ratio of the mass to charge in kg/C '? Number The comparison is done to 1% accuracy
