If the electric voltage at the ends of the conductor is 20 V, then when the 2 C charge moves from one end of the conductor to the other, the electric field does work.
The relationship between work and the potential difference (voltage) when an electric charge moves in an electric field is expressed by the formula:
A = q * U, where
q is the amount of charge in C,
U = voltage V.
A = 2 * 20 = 40 J.
Answer: when the charge moves, work is done 40 J.
