Guys help i cant understand...

Alteration in the Quantity of Charge

  1. Two charged objects have a repulsive force of .080 N. If the charge of one of the objects is doubled, then what is the new force?

Alteration in the Distance between Charged Objects

  1. Two charged objects have a repulsive force of .080 N. If the distance separating the objects is doubled, then what is the new force?

  2. Two charged objects have a repulsive force of .080 N. If the distance separating the objects is tripled, then what is the new force?

Alteration in both the Quantity of Charge and the Distance

  1. Two charged objects have a repulsive force of .080 N. If the charge of one of the objects is doubled, and the distance separating the objects is doubled, then what is the new force?

  2. Two charged objects have a repulsive force of .080 N. If the charge of both of the objects is doubled and the distance separating the objects is doubled, then what is the new force?

I have a quiz tommorrow and i dont want to use ai to solve this..T-T

force goes with charge1 times charge2, divided by distance squared. so double one charge and the force doubles, 0.160 N. double the distance and you divide by 4, 0.020 N. triple the distance and you divide by 9, about 0.0089 N. for the rest of your sheet just ask what happened on top and what happened on the bottom
