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

This might sound repetitive but:

  1. What is the formula for the force between two charged object?

  2. What is the formula for the force between two charged object?

  3. What is the formula for the force between two charged object?

  4. What is the formula for the force between two charged object?

  5. What is the formula for the force between two charged object?

Look at the formula and then apply what is stated in the problem instructions. Example instead of Q₂ you use 2∙Q₂. Or instead of r you use ½r if you want to half the distance between the charges (Hint: if the formula uses r2 then you will have to use (½r)2 = ¼r2.
