Answer: 0.064 N
Explanation:
According to <u>Coulomb's Law: </u>
Where:
is the electrostatic force
is the Coulomb's constant
and are the electric charges
is the separation distance between the charges
For the first case we have and . So, we will isolate first:
Now, for the second case, we will have the same value for , but this time and we have to find :
As we can see this value is less than because the distance between charges was increased.
