Still not sure
Using F=qE I know the q What is the F then? Is there a certain number for the gravity on the surface of the earth?
I know that F= ma, but I'm not sure where to go from this any other help would be appreciated
I have two electric field problems that I need help solving:
1. How strong an electric field is needed to support an electron against gravity on the surface of the earth?
I know the charge of an electron is -1.60 x 10^-19C
I think that you use the equation V=Ed, but I don't know what to...
If the distance between two charges is suddenly quadrupled, what happens to the electrostatic force between these charges? Not sure on this any suggestions? Thanks
Have a problem that I'm not sure how to approach any help would be appreciated!
If the electrostatic force between two protons is equal to 1x10^-7 Newtons, what is the distance between them?
I have a physics problem that I am stuck on: Approximately 4 x 10^9 kg of matter is converted into energy each second in the sun. Find the power output of the sun. I know the answer is 3.6 x 10^26 W I just can't figure out how to get the correct equation and numbers. Any help would be...
