WebScience Physics Two point charges of mass m each are suspended in the gravitational field of the Earth by two non-conducting massless strings, each of length 1, attached to the same fixed point. The spheres are given equal charges Q of the same sign. As a result each string makes angle a to the vertical (see figure below).

Webspheres in the suspension, (2.3) becomes F = AG+nS, (2.5) where n is the number of spheres per unit volume, and is related to their volume fraction by c = -7ra3n. Now the value of S for any one sphere depends on the way in which the other spheres are situated around it, and so the next step is to convert WebJul 18, 2024 · The Maxwell electric stress accounts for DEP forces and torques. This concurrence can also be explained by symmetry breaking. Even in a uniform electric field, the presence of several polarizable particles such as a suspension disturbs a local electric field around the particles and then generates a non-uniform electric field.
