2) Given:
q = 4.77 mC
d = 1.33 micro-meter
z = 28.4 cm.
The potential due to a dipole at an axis point is
[where r = distance from the center of the dipole and is much
greater than d]
Now, in our problem, instead of 'r', z is used.
therefore, the potential at the point of distance z = 28.4 cm is
[answer]
9) The relation between uniform electric field and an electric
potential is
[where r is the separation between two equipotential surfaces in
the direction of the electric field]
For conducting plates, the electric field is
Therefore, the potential difference between the two points of separation r (= 4.44 - 1.11 = 3.33 cm) is
Therefore, the magnitude of potential difference is at the separation 3.33 cm is 25.06 V. [answer]
