Two object accumulated a charge of 4.5 μc and another a charge of 2. 8 μc. these two objects are separated by a distance of 2.5 cm. calculate the magnitude of the electric force between these two objects.

181.23 C

Explanation:

According to Coulomb's Law:

Where:

 is the electrostatic force

is the Coulomb's constant  

is the charge of object 1

is the charge of object 2

is the separation distance between the charges

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.
