It can be
seen that if we separated the two charger from each other they will create a
non-zero electric field in the space. Due to this there will be some electric
field is present outside the hydrogen atom. But after some time this field will
get weaker but it is not zero outside the atom. It is given by
Outside the atom r > a
Net charge enclosed on the electron is
sum of change inside and outside.
As per Gauss’s law it becomes
It follows the rule that electric field
outside the spherical object is zero.
P2: Calculate the
capacitance and inductance per unit length between two parallel wires of
diameter d spaced D>>d apart.
Capacitance
formula
For one wire
(Williams, 2014)
P3: For the situation in problem 2 if the wires are 12 AWG
copper wire and you desire a transmission line with a characteristic impedance
of 600 Ohms what is:
a)
The distance “D” required.
Given data
Wire 12 AWG copper wire
Impedance=600 ohm
To find
Distance D
Using the characteristic impedance formula
P4: For the transmission line in problem 2 what is the
shortest length of transmission line and impedance of transmission line is
required to match a 600 Ohm Load resistance to a 50 Ohm source resistance.
P5: For ordinary borosilicate window glass 3 mm thick and
545nm light what percentage of light that is at normal incidence to the glass
makes it through the glass from the air on one side to the air on the other
side?
As we know that the refractive index of
borosilicate glass is 1.47
