Answer:
v = 17.66 m/s
Explanation:
As we know that the lower end of the pole is fixed in the ground and it start rotating about that end
so here we can say that the gravitational potential energy of the pole will convert into rotational kinetic energy of the pole about its one end
so we have
so we have
now we have
now the speed of the other tip of the pole is given as
The current is defined as the amount of charge Q that passes through a certain point of a wire in a time 
:
But the charge Q flowing in the wire is just the charge of a single electron, e, times the number of electrons N:
so the current can be rewritten as
Using
, 
(charge of one electron), and 
, we find the current:
Therefore correct answer is A).
But the charge Q flowing in the wire is just the charge of a single electron, e, times the number of electrons N:

Using
Therefore correct answer is A).
