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

Answer #1

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.

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...

The electric potential in a region of space is V=( 260 x2− 160
y2)V, where x and y are in meters. What is the direction of the
electric field at (x,y)=(2.0m,2.0m)? Give the direction as an angle
(in degrees) counterclockwise from the positive x-axis. THe
strenght of the electric field is 1200 V/m.

positive x-axis.

proton is released from rest inside a region of constant,
uniform electric field E1 pointing due North. 34.8 seconds after it
is released, the electric field instantaneously changes to a
constant, uniform electric field E2 pointing due South. 9.33
seconds after the field changes, the proton has returned to its
starting point. What is the ratio of the magnitude of E2 to the
magnitude of E1? You may neglect the effects of gravity on the
proton.

Which of the following statements is/are true regarding
behaviors of charged particles inside electric field?
Positive charges are accelerated by electric fields toward
points at higher electric potential;
If the electric field at a certain region is zero, then the
electric potential at the same region is constant;
If a negative charge moves in the direction of the electric
field, the field does positive work and the potential energy
increases
If a positive charge moves opposite to the electric field,...

In a certain region of space the electric potential is
