Amassless spring hangs from the ceiling with a small object attached to its lower end. the object is initially held at rest in a position yi
such that the spring is at its rest length. the object is then released from yi
and oscillates up and down, with its lowest position being 10 cm below yi
(a) what is the frequency of the oscillation?
(b) what is the speed of the object when it is 8.0 cm below the initial position?
(c) an object of mass 300 g is attached to the first object, after which the system oscillates with half the original frequency. what is the mass of the first object?
(d) how far below yi is the new equilibrium (rest) position with both objects attached to the spring?

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
