Antiparticles have oposite quantum numbers, so it means they also have oposite electric charge. Basicaly, they would attract as much as possible and, you know, kaboom. This is a compostite particle made of quarks, which under annihilation produce their gauge particles - gluons. These quickly undrego hadronization - will pair-up to produce mesons. These are unstable af so they decay. Ultimate fate is photons, electrons, positrons and neutrinos. Even, antiproton can annihilate with neutrons, which makes sense given similar internal structure. Keep in mind that during conversions energies are preserved. So that when lighter particles are produced, they move faster. So yes, it would be ripped apart, kind of.
