Two electricallycharges spheres are suspended from insulated threads a certain distance from each other. There is a certain amount of electrostatic force between them. Describe specifically (not just increase or decrease) what happens to this force in each of the scenarios below (1 pt. ea.):
The charge on one sphere is reduced by half
The charge on both spheres is doubled
The distance between the spheres is increased by a factor of three
The distance between the sphere is decreased to onefourth
The charge of each sphere is doubled and the distance between them is doubled

Best ResponseYou've already chosen the best response.0let's suppose to have 2 charges, namely Q_1 and Q_2, separated by a distance d. Then the interaction force F (its magnitude) is equal to: \[F = k\frac{{{Q_1}{Q_2}}}{{{d^2}}}\]

Best ResponseYou've already chosen the best response.0now, we have: scenario #1 let's suppose that the new charge is Q_1/2, then the new force is: \[{F_1} = k\frac{{\left( {{Q_1}/2} \right){Q_2}}}{{{d^2}}} = k\frac{{{Q_1}{Q_2}}}{{2{d^2}}} = \frac{F}{2}\]
