19. Two 2.0-kg spheres each carry a charge of 2.0 C. How does FE compare with Fg?
a. FE=Fg
b. Fg > FE
C.
d.
e.
FE>Fg
If the charges on the spheres are the same, then Fg > Få, but if the charges are opposite
then FE>Fg.
FE and Fg cannot be compared without knowing the distance between the spheres..](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F90502412-4b42-4711-a1f0-0436bb4aba86%2F483945de-749c-451a-a6a7-2089fbbdeba3%2Fsq7zbdw_processed.png&w=3840&q=75)
