A small object is attached to a horizontal spring, pushed to position x=−A , and then released. The object undergoes simple harmonic motion with period T. How long does it take for the object to travel a total distance of 3A ? 12T 14T T 34T 54T Now assume that the object is initially at x=0 and given an initial velocity such that it oscillates with the same amplitude A. Relative to your previous answer, how much does the time to travel 3A change under these new conditions? The time will increase by 12T . The time will increase by 14T . The time will decrease by 12T . The time will decrease by 14T . No change in the answer.

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=14πϵ0. d)the ball will oscillate along the z axis between z=d and z=−d in simple harmonic motion. what will be the angular frequency ω of these oscillations? use the approximation d≪a to simplify your calculation; that is, assume that d2+a2≈a2. express your answer in terms of given charges, dimensions, and constants
