Suppose you are hiking along a trail. make a comparison between the magnitude of your displacement and your distance traveled. check all that apply. check all that apply. the magnitude of your displacement must be equal to your distance traveled. the magnitude of your displacement must be greater than your distance traveled. the magnitude of your displacement must be less than your distance traveled. the magnitude of your displacement can be less than your distance traveled. the magnitude of your displacement can be equal to your distance traveled. the magnitude of your displacement can be greater than your distance traveled.

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
