Question

Define Electric field

A. Two charges of equal magnitude and opposite signs separated by a distance

B. unit of electric field

C. property of a material that is directly proportional to the resistance of the material

D. ratio of electric force to charge

E. None of the above

ANSWER:

Answer #1

A) Two charges of equal magnitude and opposite sign separated by a distance is called an Electric dipole.

B) Unit of electric field is :

C) Resistivity is an intrinsic property of a material and directly proportional to the total resistance.

D) Ratio of electric force to charge can be electric field. Because electric field due to an electric charge is nothing but force experienced by a unit positive charge situated at some distance from the electric charge.

Two large, parallel, metal plates carry opposite charges of
equal magnitude. They are separated by a distance of 45.0 mm , and
the potential difference between them is 365 V
(A) What is the magnitude of the electric field (assumed to be
uniform) in the region between the plates?
(B) What is the magnitude of the force this field exerts on a
particle with a charge of 2.10 nC ?
(C) Use the results of part (b) to compute the...

Two point charges of the same magnitude but opposite signs are
fixed to either end of the base of an isosceles triangle, as the
drawing shows. The electric field at the midpoint M
between the charges has a magnitude
EM. The field directly above the
midpoint at point P has a magnitude
EP. The ratio of these two field
magnitudes is
EM/EP =
6.29. Find the angle ? in the drawing.

The electric field midway between two equal but opposite point
charges is 715 N/C , and the distance between the charges is 29.7
cmcm . What is the magnitude of the charge on each?

15.3 Two equal point charges are separated by a distance of 23
cm. The magnitude of the force that one charge exerts on the other
is 18 N. What is the charge?
15.4 A 5 μC charge and a 3 μC charge are separated by some
distance. If the magnitude of the force that one charge exerts on
the other is 27 N, what is the distance between the two
charges?

QUESTION 5
Determine which of the following statements is true about
electric field lines in the vicinity of two point charges of equal
magnitude and opposite sign
a. they are small according to the magnitude of the loads
decrease
b. does not depend on the magnitude of the loads
c. indicate the relative magnitude of the electric field
d. indicates the direction of the electric field
e. is larger as the magnitude of the loads increases

For a...

Two point Charges, q and -q, are separated by a distance d, both
being located at a distance d/2 from the infinite conducting plane.
What is the magnitude of the electric force action on each charge?
Find the magnitude of the electric field at the midpoint between
these charges?
Reference: In this instance the Conducting plate Separates -q
and q (which is d distance apart above the conducting plate). The
conducting plate is d/2 distance below the charges -q and...

Problem 1
Two charges are placed in an electric field a distance r from
each other. Charge q1 is positive while charge q2 is negative.
Select all possible changes that will double the electric force
between the two charges:
(a) change the sign of q2
(b) half the magnitude of q1 and half of r
(c) double the magnitude of q2 and take half of r
(d) take half of r
(e) double the magnitude of one of the charges...

Two particles having charges of 0.430 nC and 3.87 nC are
separated by a distance of 1.20 mm.
1)At what point along the line connecting the two charges is the
net electric field due to the two charges equal to zero? Express
your answer in meters.
2)Where would the net electric field be zero if one of the
charges were negative? Enter your answer as a distance in meters
from the charge initially equal to 0.430 nC.
3)Is this point...

Two point charges, A and B, are separated by a distance of 19.0
cm . The magnitude of the charge on A is twice that of the charge
on B. If each charge exerts a force of magnitude 46.0 N on the
other, find the magnitudes of the charges.
