You have a pair of cannon balls, each 100kg in mass, and a ‘charge shuttling’ device which can be used to remove electrons from one object and place them on another. One of the cannon balls is suspended from the ceiling with an insulating cord. You want to use electrostatic attraction to cause the other to hang in space beneath it, just by removing electrons from the upper cannon ball, and placing them on the lower one. How many electrons must you "shuttle" in order to get the lower cannon ball to hover 2.0m below the upper one? Give your answer in moles.

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
