Answer to Question #82778 in Electricity and Magnetism for Xyree

Question

Two objects are both negatively charged with 0.02 each and are 70 cm apart. What kind of force exist between them and how much?

Answer 1

F=1/(4πε_0 ) |q||q|/R^2 →1/(4π∙8,85×〖10〗^(-12) ) 〖0,02〗^2/〖0,7〗^2 =1/(1,11×〖10〗^(-10) ) (4×〖10〗^(-4))/(4,9×〖10〗^(-1) )=7,3×〖10〗^6 N
