Question

please explain why!!

1. An electron is released from rest in a region of space with a
nonzero electric field. As the electron moves, **does the
electric potential energy of the system increase or
decrease**? Explain.

2. An electron is released from rest in a region of space with a
nonzero electric field. As the electron moves, **does the
electron move from a position of high to low electric
potential**? Explain.

Answer #1

1)

The electron is released from rest in a region of space with an electric field .

Electron moves in opposite direction to electric field, from lower to higher potential.

Change in potential energy is

But Potential

That is **electrical potential energy** of the
system is **decreasing.**

**2)**

As electron is negatively charged particle,

Force on the electron is

Direction of electron is in the opposite direction of electric field.

The direction of electric field is from higher to the lower potential.

That is electron moves from **lower potential to higher
potential.**

1. A proton is released in a region in space
where there is an electric potential. Describe the subsequent
motion of the proton.
2. In a certain region of space, the electric field is zero.
From this fact, what can you conclude about the electric potential
in this region? (a) It is zero. (b) It does not vary with position.
(c) It is positive. (d) It is negative. (e) None of those answers
is necessarily true.
please provide throughout explanation

QUESTION When an electron is released from rest in a constant
electric field, how does the electric potential energy associated
with the electron, and the kinetic energy of the electron, change
with time? (Select all that apply.)
options:The electric potential energy becomes more negative.The
electric potential energy becomes more positive.The kinetic energy
becomes more negative.The kinetic energy stays the same.The
electric potential energy stays the same.The kinetic energy becomes
more positive.
Use the worked example above to help you solve...

The electric potential in a region of space as a function of
position x is given by the equation V(x) =
αx2 + βx - γ, where α =
2V/m2, β = 7V/m, and γ =
15V. All nonelectrical forces are negligible.
An electron starts at rest at x = 0 and travels to
x = 20 m.
Calculate the magnitude of the work done on the electron by the
electric field during this process.
Calculate the speed of the...

An electron with kinetic energy 4.0 keV moves horizontally into
a region of space in which there is a downward-directed electric
field of magnitude 14 kV/m.
(a) What are the magnitude and direction of the (smallest)
magnetic field that will cause the electron to continue to move
horizontally? Ignore the gravitational force, which is rather
small.

Consider a charge of -0.3 C which is moved from a point in space
at electric potential V=3 volts to one at V=1 volts. The charge
begins at rest and ends at rest.
a)Along the way, does the average electric field point more or
less toward the final point, or more or less away from it, on
average? Justify your answer.
b) Along the way, does the average electric force point more or
less toward the final point, or more...

Protons are released from rest in a Van de Graaff accelerator
system. The protons initially are located where the electric
potential has a value of 5.95 MV and then they travel through a
vacuum to a region where the potential is zero.
(a) Find the final speed of these protons.
m/s
(b) Find the accelerating electric field strength if the potential
changed uniformly over a distance of 2.60 m.
MV/m

An electron is initially at rest in a uniform electric field
having a strength of 1.95 × 106 V/m. It is then released
and accelerated by the presence of the electric field.
What is the change in the electron’s kinetic energy, in
kiloelectron volts, if it travels over a distance of 0.25 m in this
field?
Over how many kilometers would it have to be accelerated in the
same electric field to increase its kinetic energy by 65 GeV?
