Two point charges attract each other with an electric force of magnitude f. if one charge is reduced to one-third its original value and the distance between the charges is doubled, what is the resulting magnitude of the electric force between them? a) 3f/2b) f/3c) f/6d) f/12e) 3f/4

New force,

Explanation:

Given that, two point charges attract each other with an electric force of magnitude F. It is given by :

If one charge is reduced to one-third its original value and the distance between the charges is doubled such that,

,

So, the electric force between them is reduced to (1/12). Hence, the correct option is (d).

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
