Objects 1 and 2 attract each other with a electrostatic force of 36.0 units. If the distance separating Objects 1 and 2 is

changed to one-half the original value (i. e., halved), then the

new electrostatic force will be units.

F = 144 units

Explanation:

For this exercise we use coulomb's law, for the initial conditions

           F₀ =

indicate that the force F₀ = 36.0 units and the distance is reduced to r = r₀/2 which is the new force

          F =

we substitute

          F = 4

          F = 4 F₀

we calculate

          F = 4 36

          F = 144 units

i need the answer to this too but idk it ; -;

it is called kinetic energy
