Question

i need help!

Answer 1

During a thunder storm, movement of water molecules within clouds creates friction which causes the bottom of the clouds to become negatively charged. This means that the bottom of the cloud and the ground begin to act like parallel plates. Once the electric field between the clouds and the ground becomes larger than 3.0 x 10^6 N/C, lightning will strike.
a. If the bottom of the cloud is 150 m above the ground, determine the electric potential difference between the ground and the cloud.

b. Say 6.24 x 10^18 electrons move between the ground and the cloud during a lightning strike. How much electric potential energy does this represent? Are the electrons gaining or losing energy?

Answer 4

potential difference = (electric field) * (distance)

Answer 5

simply multiply electric field and distance between the points to get the potential difference between the points

Answer 6

a) V=Ed
=3.0 x 10^6 N/C X 150 m
=450000000.

Answer 7

am I doing it right?

Answer 12

The second part says we have 6.24*10^18 electrons, each of which contribute 1 eV. It just so happens that there are 6.24*10^18 eV in 1J, so the answer is 1J. Because electric potential energy is measured in joules, unlike for electric potential which uses voltage (joules per coulomb)

Answer 13

And also since the electrons used up their potential energy during the move, they lost energy

Answer 14

well thanks a lot and I appreciated
