... Answer[D]: Think of the 2Q object as two Q charges on top of each other. At point B both of the field vectors from the two Q charges are aligned so the net field is just the sum. At point A they are not aligned so the electric field is less. The contribution to the potential depends only on the dist ...

... In the early 1900’s, research on the theory of quantum tunneling, as well as experiments discerning the masses of light elements, led to the discovery that large amounts of energy can be produced by fusing light nuclei. This release in energy can be attributed to the relative strengths of the Coulom ...
