Document Summary
Please read the problems carefully and answer them in the space provided. Write on the back of the page, if necessary. In the following, four physical situations are sketched for you. In each case determine the direction of the force or current as requested. Your choices in each case are: zero, left, right, up, down, into paper, out of paper, clockwise, counter-clockwise. If the resistance for a simple series rlc circuit is increased, the resonant frequency of that circuit (provided it still readily oscillates: is increased, is decreased, remains unchanged, insufficient information is give for a response. A spherical balloon contains a positively charged particle at its center. As the balloon is inflated to a greater volume while maintaining the charged object at the center, the electric potential at the surface of the balloon increases while the electric flux through the balloon"s surface decreases.
