Lithography works because of the mutual repulsion of oil and water.
For example, it is not feasible to construct a weapon using positrons alone, due to their mutual repulsion.
For example, the mutual repulsion between molecules has the effect of excluding neighbors from a certain amount of space around each molecule.
These start infinitely far apart and then are pushed towards each other, doing work against their mutual electrostatic repulsion.
The helium nuclei there are obviously engaged despite their mutual electrical repulsion.
Electrostatic stabilization is based on the mutual repulsion of like electrical charges.
Thus, the two determinants behave as if they exert mutual repulsion upon one another.
Any charge on the object will flow into the ground due to its mutual repulsion.
They also used mutual repulsion to keep the chunks evenly distributed in a disk, rather than accreting into planetary bodies.
The mutual repulsion is slightly reduced between two electrons, though, if they have opposite spins.
