Which change increases the electric force between objects? two neutral objects are moved closer together. electrons are added to two negatively charged objects. two oppositely charged objects are moved farther apart. the charge on two positively charged objects is reduced.

Individuals who live below the poverty line get seriously ill more often than those who do not what could be the hidden variable in this situation?

Place me with this question is my last question

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?
