Can a system have negative potential energy? No, because a negative potential energy is unphysical. No, because the kinetic energy of a system must be equal to its potential energy. Yes, as long as the total energy remains positive. Yes, as long as the total energy remains negative. Yes, because the choice of the zero of potential energy is arbitrary.

Because this energy is an electric potential energy, it must be associated with a force. For any potential energy: F=-U. In other words, there is a force in the direction of decreasing potential energy. What does this mean for the dielectric as it begins to enter the capacitor?

1) You move a negative charge relative to a positive charge, such that the potential energy between the two decreases. Gravity should be ignored. This means you must be: a)Bringing them closer to one another b)Moving them apart c)Either or d)Cannot be determined 2) The amount of work needed to create a dipole of charge Q and distance a is: a) −kQ^2/a b) kQ2/a c) None of the above

The stock prices of energy companies have tumbled (mainly because of a collapse in energy prices) to lows we haven’t seen in years. As a result the dividend yields of these companies have skyrocketed. BP, as of today, is paying greater than a 10 percent dividend to its shareholders. Exxon and some other major oil companies have similar dividend yields. This can be lure to investors because of a very low interest rate environment, a risky stock market (at the...
