Honors Physics Worksheet  Coulomb's Law
This worksheet is designed to assess your understanding of Coulomb's law.

A  B 
The force of attraction between two charges is 3.4 x 10^2 N. If each charge is doubled, what would the new force of attraction be?  ??? 
What is the force of attraction between a proton and an electron separated by 1.2 x 10^10 m?  ??? 
The force on two charges separated by 1.2 x 10^5 m is 5.6 x 10^8 N. If one charge is 45 microcoulombs, what is the other charge?  ??? 
The force of repulsion between two like charges is 3.4 x 10^6 N. If the charges are separated by a distance of 24 nm, what is the value of each charge?  ??? 
What is the force of attraction between two charges, 25 microcoulombs and 120 millicoulombs, separated by a distance of 400 nm?  ???
