The electric field at the surface of a charged, solid, copper sphere with radius 0.200 m is 3800 N>C, directed toward the center of the sphere.

Now the elevator is moving downward with a velocity of v = - 2.8 m/s but accelerating upward with an acceleration of a = 5.5 m/s2. (Note: an upward acceleration when the elevator is moving down means the elevator is slowing down.
