That seems like a statement more than a question. Where's the question?
Some examples of insulators are plastic, glass and rubber.
Electric potential energy of a dipole is given as


so change in the potential energy is given by


here initially it was parallel to electric field while finally it is perpendicular to the electric field
so we have


so above is the change in potential energy of dipole
Answer: 226.2 m
Explanation:
If we want to find the new total height
of the building, we have to add to its initial height
the height of the antenna
, as follows:


Then:
This is the new total height of the building.
The answer is b/ cope a small section word-for-word
