Abstract
Work is devoted to study of physics of deformation of a charged water drop with application of numerical methods, in approach of its ellipsoidal form. The criterion of instability of a drop versus the size of its initial deformation is investigated. It is shown that at small initial disturbances, the time of development of instability considerably exceeds the period of vibrations of a non-disturbed uncharged drop. The time of instability exponentially decreases with an increase in initial deformations. This indicates an important role of external factors of deformations of charged drops leading to acceleration of their instability.
