After studying this chapter the students will be able to
state Coulomb's ·law and explain that force between two
point charges is
reduced in a medium other than free space using Coulomb's
law.
derive the expression E = l/41re0 qi? for the magnitude of
the electric field
at a distance 'r' from a point charge 'q'.
describe the concept of an electric field as an example of a
field of force.
define electric field strength as force per unit positive
charge.
solve problems and analyse information using E = Flq.
solve problems involving the use of the expression E =
U41rio qi?.
calculate the magnitude and direction of the electric field
at a point due to
two charges with the same or opposite signs.
sketch the electric field lines for two point charges of
equal magnitude
with same or opposite signs.
describe the concept of electric dipole.
define and explain electric flux.
describe electric flux through a surface enclosing a charge.
state and explain Gauss's law.
describe and draw the electric field due to an infinite size
conducting plate
of positive or negative charge.
sketch the electric field produced by a hollow spherical
charged
conductor.
sketch the electric field between and near the edges of two
infinite size ~
oppositely charged parallel plates.
define electric potential at a point in terms of the work
done in bringing
unit positive charge from infinity to that point.
