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

9.0 units

Explanation:

The magnitude of the electrostatic force between two charged objects is given by Coulomb's law:

where:

is the Coulomb's constant

are the two charges  of the two objects

r is the separation between the two charges

The force is:

- Attractive if the charges have opposite signs

- Repulsive if the charges have same sign

In this probleem, the initial force between the two objects is

F = 18.0 units

Then, the charge of object 1 is halved, so the new charge is

Therefore the new force is

So, the force will also halve: therefore, the new force will be 9.0 units.

answer: i'm not sure which is which for i get confused on it all the time but i can tell you that the answer lies with the convex and concave devices. i hope this you. have a good day and best of luck to you!
