Betty asks…physics 11 force question?What is the F=kQq /R^2 formula?
What is k? How do you figure out the force when (R) between the two charges Q and q increase from 5m to 5.5 m when you know that the force between the two charges Q and q is 5.1x10^-8 N when it's separated by the 5m one?
please explainNancy answers:"What is the F=kQq /R^2 formula?"
It's the equation for the electrical force between any two charges Q and q.
"What is k?"
It's an empirical constant equal to 8.99 x 10^9 in
