• ### Method of image chargesWikipedia

The method of image charges (also known as the method of images and method of mirror charges) is a basic problem-solving tool in electrostatics.The name originates from the replacement of certain elements in the original layout with imaginary charges which replicates the boundary conditions of the problem (see Dirichlet boundary conditions or Neumann boundary conditions).

The electric charge of two up quarks and a down quark does add up to the charge of a proton up quark ( 2/3) up quark ( 2/3) down quark (-1/3) = proton ( 3/3 = 1) No problem there. But you re right that the masses of the three quarks don t add up to anywhere near the mass of a proton. A proton is almost 100 times heavier than the three quarks
