Electric Field and Electric Force

Question 1

In a uniform electric field, a charge will experience an electric force
described by the following equation:

Answer 1

F = Eq

Question 2

Since electric field is a vector quantity, we can always use a free-body diagram as part of our analysis.

Answer 2

True

Question 3

If we get the sum of all of the
y-components of the electric field
caused by the individual charges
along the line segment, it will just
be equal to zero.

Answer 3

cylindrical symmetry.

Question 4

for a line charge distribution. It
has a unit of C/m.

Answer 4

Linear charge density, λ (lambda)

Question 5

for a distribution over a surface.
It has a unit of C/m2.

Answer 5

Surface charge density, σ (sigma)

Question 6

for a distribution through a volume.
It has a unit of C/m3.

Answer 6

Volume charge density, ρ (rho)

Question 7

The net electric field can be solved using the _____.

Answer 7

superposition of electric field

Question 8

can be helpful in simplifying problems in a
uniformly distributed charge source or system of charges.

Answer 8

Symmetry

Question 9

are described by linear charge
density λ, surface charge density σ, and volume charge density ρ.

Answer 9

Charge distributions
