(D)
Explanation:
Given :
l=3.5 m
Resistance can be calculated as :
Resistance of the wire will be 1.1× ohms
Option D is correct
One charge is enough in order to have an electric field.
In fact, every charge generates an electric field: for example, the electric field generated by a single point positive charge is radial, as shown in the attached figure. More complicate electric field configurations can be obtained adding charges or using more complicate charge distributions, but one charge is enough to have an electric field.
