D.) Conservation of Charge – net __________ of closed system ____________
ex. If 2 charges are brought together their
combined charge is ___________
***
Total ___________ = total ____________ after
Charges
come in ____________ of ___________________ Coulombs
Proton +1.6 X 10-19 C : Ref.
Electron - _____________ C : Ref.
Coulombs Law – Calculating the forces between two fixed point charges
F - __________ force of
attraction or repulsion
(
q - ______________of each object
r -
__________________ between objects
(On
______________________) k- electrostatic constant = _______________
F=[kq1q2]/(r2)
Ex) What is the electrical force between 2 very small
objects located .5m apart when the charge on one object is 4X10–8 C
and the charge on the second object is 6X10 -5 C ?

Two charges attract each
other with a force of F. If one charged
was doubled and the other charged
was tripled, how would that change
the attractive force between these charges?
