A 1-kg block is stacked on top of a 2-kg block that rests on the ground. Denote the 1-kg block as block one and the 2-kg block as block two. Rank from greatest to least the magnitudes of the forces: FEM1/E the electromagnetic force block one exerts on the Earth FG1/E the gravitational force block one exerts on the Earth FEM2/E the electromagnetic force block two exerts on the Earth FG2/E the gravitational force block two exerts on the Earth and F/2 the force block one exerts on block two
