A charge of #2 C# is at #(9,1 )# and a charge of #1 C# is at #( 2,5 )#. If both coordinates are in meters, what is the force between the charges?
1 Answer
Answer:
Explanation:
The electric force
where

#epsilon_0# is a physical constant called the permittivity of free space, equal to#8.8542 xx 10^12 (C^2)/(N*m^2)# , and 
#r# is the distance (in#"m"# ) between the two point charges.
To find the distance between the two charges, we can use the distance formula:
Now that we have all the necessary variables, let's plug them into the equation to find the charge:
Thus, the electric force between the two point charges is
