rst, launch the video below. You will be asked to use your knowledge of physics to predict the outcome of an experiment. Then, close the video window and answer the questions at right. You can watch the video again at any point. Part A Consider the video demonstration that you just watched. A more complete explanation of what you saw will be possible after covering Newton's laws. For now, consider the following question: How would the result of this experiment change if we replaced the ball with another one that had half the mass? Ignore air resistance.

Consider a uniformly charged ring in the xy plane, centered at the origin. the ring has radius a and positive charge qdistributed evenly along its circumference. a)what is the direction of the electric field at any point on the z axis? . b)what is the magnitude of the electric field along the positive z axis? use k in your answer, where k=14ΟΟ΅0. d)the ball will oscillate along the z axis between z=d and z=βd in simple harmonic motion. what will be the angular frequency Ο of these oscillations? use the approximation dβͺa to simplify your calculation; that is, assume that d2+a2βa2. express your answer in terms of given charges, dimensions, and constants
