A point charge is released from rest in a region containing an electric field. The charge will start to move: (A) in a direction that makes its potential energy increase (B) in a direction that makes its potential energy decrease (C) along a path of constant potential energy (D) Either A or B, depending on the sign of the point charge

Problem1.

A) Asmall negative charge is released from rest inan electric field.Will the charge move toward a region of

higher orlower potential energy? Will the chargemove toward a region ofhigher or lower voltage?

B) Inwhat direction, relative to the direction ofan electric field, isthe voltage constant?

An electron is released from rest in a region of space with a nonzero electric field.

1. As the electron moves, does the electric potential energy of the system increase, decrease, or stay the same?
 
a. increase
b. decrease
c. stay the same

2. Choose the best explanation from among the following.

a. As the electron begins to move, its kinetic energy increases. The increase in kinetic energy is equal to the decrease in the electric potential energy of the system.
b. Because the electron has a negative charge its electric potential energy doesn't decrease, as one might expect, but increases instead.
c. The electron will move perpendicular to the electric field, and hence its electric potential energy will remain the same.

if the electric potential at point a is +30.0 v, what is the electric potential at point b?

An object with charge q = −7.00×10−9 C is placed in a region of uniform electric field and is released from rest at point A. After the charge has moved to point B, 0.500 m to the right, it has kinetic energy 5.00×10−7 J .

A) If the electric potential at point A is +30.0 V, what is the electric potential at point B?

B) What is the magnitude of the electric field?
