gravitational force can be evaluated for the interaction between
protons and electrons. Which is dominant?
a. The gravitational force
b. The electric force
c. Both forces are approximately equal
d. Neither force is very strong at the atomic level
e. Two of the above are correct
2. A student rubs a balloon in her hair then holds the balloon
against a wall and finally releases it after a moment....
2.Why do we need the concepts Force and Electric field? What are
they?
Why electric field lines never intersect?
What are electric dipole and electric dipole moment?
Define electric potential energy of an electric dipole.
What are stable and unstable equilibrium
positions for an electric dipole?.
What is the magnitude and direction of an electric field if it
exerts a downward force of 10-6N on a charge of -5μC?
Could you please explain how to do this question? Thank you
An electron is released in a uniform electric field, and it
experiences an electric force of 2.2 ✕ 10-14 N downward.
What are the magnitude and direction of the electric field?
Magnitude
____________ N/C
Direction
upward, to the left, to the right or downward?
electric field and electric potential. To understand the
formative properties of charges on the electric fields that were
formed and the relationship between electric fields and electric
potential.
Here are two question from anaysis part, can you answer them in
general.
3.) Discuss the results of each of the three conductive sheets
in terms of (1) the propertiesof electric field lines, (2) the
properties of equipotentials, and (3) properties ofconductors
listed in the Background Information section. How do the shapes...
Which of these statements comparing electric and gravitational forces is correct?(a) The direction of the electric force exerted by one point particle on another is always the same as the direction of the gravitational force exerted by that particle on the other.(b) The electric and gravitational forces exerted by two particles on each other are inversely proportional to the separation of the particles.(c) The electric force exerted by one planet on another is typically stronger than the gravitational force exerted...
(a) Use Gauss’s Law for the electric field to show that the
electric field is discontinuous at the charged surface of a
conducting plane.
(b) Devise a way to apply this same approach to a patch on a
charged spherical conductor. Hint: Draw a diagram with the electric
field so you can specify the shape of the surface.
