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 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...

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.

Two point charges, A and B, are separated by a distance of 23.0
