Explanation:
According to the figure,
Formula to calculate net dipole moment is as follows.
=
= C-m
Therefore, we can conclude that the net dipole moment for given water molecule is C-m.
Answer:
The potential at the point 8 meters is approximately 48.98 Joules/C
Explanation:
Notice that we need to find the potential at a point aligned to the rod's axis (see attached figure), that is located 6 meters from one end of the rod. Notice as well, that the length (L) of the rod is 5 meters.
Since we have a uniformly distributed charge, the charge density per unit of length is defined as:
In order to find the contribution of each little segment dx of charge
to the potential at the requested point, we need to perform an integral:
