Chapter 24: Q2P (page 710)

The electric potential difference between the ground and a cloud in a particular thunderstorm is 1.2脳109V. In the unit electron-volts, what is the magnitude of the change in the electric potential energy of an electron that moves between the ground and the cloud?

Short Answer

Expert verified

The magnitude of the change in the electric potential energy of an electron is 鈭�U=1.2GeV.

Step by step solution

01

Given data:

The electric potential difference between the ground and a cloud in a particular thunderstorm is,

鈭�V=1.2脳109V

02

Understanding the concept:

The potential difference is the change of potential energy per unit charge.

Using potential energy equation

U=qV

Here, U is the potential energy, q is the electric charge, and V is the potential.

03

The magnitude of the change in the electric potential energy:

Calculatethe magnitude of the change in the electric potential energy of an electron that moves between the ground and the cloud.

鈭�U=e鈭�V=1.2脳109eV=1.2GeV

Hence, the magnitude of the change in the electric potential energy of an electron is 1.2 GeV.

Figure 24-30 shows a system of three charged particles. If you move the particle of chargefrom point Ato point D, are the following quantities positive, negative, or zero: (a) the change in the electric potential energy of the three particle system, (b) the work done by the net electric force on the particle you moved (that is, the net force due to the other two particles), and (c) the work done by your force? (d) What are the answers to (a) through (c) if, instead, the particle is moved from Bto C?

Question: An electron is placed in an x-yplane where the electric potential depends on xand yas shown, for the coordinate axes, in Fig. 24-51 (the potential does not depend on z). The scale of the vertical axis is set by Vs=500 V. In unit-vector notation, what is the electric force on the electron?
