Near the surface of the Earth, a particle with mass m and charge q hovers above an infinite plane with charge density σ. The force gravity on the particle is exactly cancelled out by the upward repulsion from the plane.    (ε and g have their usual meanings.) The surface charge density σ is: a) εq/mg b) 2εq/mg c)εmg/q d)2εmg/q
