Problem 4 (25 pts) - A pair of parallel plates is given equal and opposite surface charge density 0 = 4.2 uCImZ. A sphere of charge Q is placed between plates and released from rest. A) Write down the vector form of the electric field between the plates using unit vectors (8 points) if 2592+ E 3; B) If the sphere moves a distance d = 0.1.1 meters after being released, calculate the work done by on the sphere (9 points) C) At the end of this motion, the sphere is moving at 1.1 m/s. Calculate the charge (in Coulombs) on the sphere assuming its mass is 0.1 kg (8 points) +++++++++++
