Objects 1 and 2 attract each other with a electrostatic force of 18.0 units. If the charge
of Object 1 is doubled AND the charge of object 2 is tripled, then the new electrostatic
force will be units.

new force is 6 times of the initial force.

Explanation:

Let the charges on two objects is q₁ and q₂. The electric force between charges is given by :

Objects 1 and 2 attract each other with a electrostatic force of 18.0 units

If the charge  of Object 1 is doubled and the charge of object 2 is tripled, it means, and . New force is given by :

So, the new electrostatic force between objects will become 6 times of the initial force.

i believe the answer would be:
