An electric field at a spatial point does NOT depend on: (Choose all the answers)
a. the distance from the source of the electric field
b. the kinetic energy of test charge
c. the charge distribution
d. the direction of the point from the source
e. the charge carried by a test charge
Homework Answers
Answer: (b), (c)
The electric field at position 
due to a charge distribution 
is given by
where integration is over the charge distribution.
The electric field depends on :
1. distance of the source of the electric field which is
in the above formula
2. the charge distribution, which is
in the formula
3. the direction of the point from the point of source, which is
contained in 
in the numerator.
The electric field DOES NOT depend on:
b. the kinetic energy of test charge
e. the charge carried by a test charge

An electric field can be created by a single charge or a distribution of charges. The electric field a distance from a point charge has magnitude E = k|q'|/r^2. The electric field points away from positive charges and toward negative charges. A distribution of charges creates an electric field that can be found by taking the vector sum of the fields created by individual point charges. Note that if a charge is placed in an electric field created by q',...

Consider a positive source charge Q, that is being held in
place. A nearby negative test charge q moves from point A to point
B.
a) What is the direction of the electric force that the source
charge exerts on the test charge?
b) As the negative test charge moves from point A to point B,
does the electric force cause it to speed up, slow down, or move at
a constant velocity?
c) As the negative test charge moves...

Incorrect Question 9 0/1 pts Choose the correct statement concerning electric field lines: At any point, the electric field lines are vectors in the direction of the electric field None of these answers are correct. At any point, the electric field is parallel to the tangent to a curved field line at that point Electric field lines are trajectories of a test charge. Electric field lines point away from negative charge.

An electric field can be created by a single charge or a distribution of charges. The electric field a distance r from a point charge q' has magnitude {E}=k\frac{|q'|}{r^2}. The electric field points away from positive charges and toward negative charges. A distribution of charges creates an electric field that can be found by taking the vector sum of the fields created by individual point charges. Note that if a charge q is placed in an electric field created by...
