# Two charges of # -1 C # and # -3 C # are at points # (-2 ,4,-3 ) # and # ( -3, 5,-81 )#, respectively. Assuming that both coordinates are in meters, what is the force between the two points?

##### 1 Answer

#### Explanation:

The electric force

where *Coulomb's law constant*, equal to

To find the distance between the two objects, we simply find the distance between the two coordinate points by

Since we have all our known variables, let's plug them in to the equation
