During a particular thunderstorm, the electric potential difference between a cloud and the ground is Vcloud - Vground = 1.10 108 V, with the cloud being at the higher potential. What is the change in an electron's electric potential energy when the electron moves from the ground to the cloud?

Well, let's see here. If the electron is moving from the ground to the cloud, that means it's moving against the electric field. It's like going against the flow, swimming upstream, or trying to get people to use turn signals while driving - not an easy task!

Now, the change in electric potential energy is given by the equation ΔPE = q ΔV, where ΔPE is the change in potential energy, q is the charge, and ΔV is the change in electric potential. In this case, the charge of an electron is -1.6 x 10^-19 Coulombs and the change in electric potential is 1.1 x 10^8 Volts.

So, plugging in the values, we get ΔPE = (-1.6 x 10^-19 C) x (1.1 x 10^8 V). Crunching the numbers, we find that the change in electric potential energy is approximately -1.76 x 10^-11 Joules.

Well, ain't that a shocker! The electron loses some electric potential energy as it moves against the electric field. But hey, at least we managed to sneak in a physics lesson while having a little fun, right?

To find the change in an electron's electric potential energy when it moves from the ground to the cloud, we can use the formula for electric potential energy:

ΔPE = qΔV

Where:
ΔPE is the change in electric potential energy
q is the charge of the electron (which is the elementary charge, e, or approximately 1.6 x 10^-19 C)
ΔV is the change in electric potential (in volts)

In this case, we are given that the electric potential difference between the cloud and the ground is Vcloud - Vground = 1.10 x 10^8 V.

Therefore, the change in electric potential, ΔV, is 1.10 x 10^8 V.

The charge of an electron, q, is -1.6 x 10^-19 C (since electrons have a negative charge).

Substituting these values into the formula:

ΔPE = (-1.6 x 10^-19 C)(1.10 x 10^8 V)
= -1.76 x 10^-11 J

The change in the electron's electric potential energy when it moves from the ground to the cloud is approximately -1.76 x 10^-11 Joules. The negative sign indicates that the electron loses potential energy as it moves to the higher potential.
