When an object with an electric charge of -0.770 m is 61.0 m away from an object with an electric charge of 0.190 mC, the electric potential energy is measured to be -21.56 J.
Calculate the electric potential energy of this system when the objects are 122. m apart.
Be sure your answer has a unit symbol and round your answer to 3 significant digits.

Answer is: the equilibrium  shifts toward the reactants, to the left side of chemical reaction.it is because lead(ii) nitrate dissociates in water: pb(no₃)₂ → pb²⁺(aq) + 2no₃⁻(aq).according to lechatelier's principle, the position of equilibrium moves to counteract thechange (more lead cations, common ion), the position of equilibrium will move so that the concentration ofproducts decrease and concentration of reactants of chemical reaction increase.read more on -

The question is incomplete. complete question is attached belowanswer: correct answer is option b  i.e.  solid particles  reason: filter paper has small pores, through which smaller particles can pass through. however, solid particles  have relatively larger size. hence, they are least likely to pass through.
