During a particular thunderstorm, the electric potential difference between a cloud and the ground is Vcloud - Vground = 4.3 108 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?

Question

During a particular thunderstorm, the electric potential difference between a cloud and the ground is Vcloud - Vground = 4.3 108 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?

Answer 1

Multiply the potential difference (in volts) by the electron charge (in Coulombs). The answer will be in Joules.

Put a minus sign in front of it since the potential energy of the electron drops when it moves to higher positive potential.

Answer 2

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

Change in electric potential energy (ΔPE) = q * ΔV

where q is the charge of the electron and ΔV is the change in electric potential.

1. The charge of an electron is given as e = 1.6 x 10^-19 C (Coulombs).
2. The change in electric potential (ΔV) is given as Vcloud - Vground = 4.3 x 10^8 V.

Now, let's substitute these values into the formula:

ΔPE = (1.6 x 10^-19 C) * (4.3 x 10^8 V)

Calculating the expression:

ΔPE = 6.88 x 10^-11 Joules

Therefore, the change in an electron's electric potential energy when it moves from the ground to the cloud is 6.88 x 10^-11 Joules.

Answer 3

To find the change in an electron's electric potential energy when it moves from the ground to the cloud, first, we need to determine the charge of an electron, the electric field, and the distance over which the electron moves.

The charge of an electron is given by the elementary charge, which is 1.6 x 10^-19 C.
The electric field can be calculated using the given potential difference and the distance over which the potential difference exists.
However, the distance between the cloud and the ground is not provided in the question.

Once we have the electric field, we can use the equation for electric potential energy to find the change in an electron's electric potential energy.

The equation for electric potential energy is given by:
ΔPE = qΔV
Where ΔPE represents the change in electric potential energy, q represents the charge, and ΔV represents the potential difference.

However, without the distance, it is not possible to determine the electric field and consequently, the change in the electron's electric potential energy.

So, in order to answer the question, we would need the distance between the cloud and the ground.

During a particular thunderstorm, the electric potential difference between a cloud and the ground is Vcloud - Vground = 4.3 108 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?

Multiply the potential difference (in volts) by the electron charge (in Coulombs). The answer will be in Joules.
