25. A helium ion with a charge of +2e is accelerated to move 2.0 coulombs of charge from point A 24. In an electric field, 6.0 joules of work are done to point B. Calculate the potential difference between points A and B. 25. A helium ion with a charge of +2e is accelerated by a potential difference of 5.0 × 103 volts. What is the kinetic energy acquired by the ion? (1) 3.2 x 10-19 ev (2) 2.0 ev (3) 5.0 x 103 ev (4) 1.0 x 104 ev 26. Calculate the potential difference across a 6-ohm resistor if 4 joules of work are required to move 2 coulombs of charge through the resistor. 27. An electron is accelerated from rest through a potential difference of 200. volts. What is the work done on the electron in electronvolts?
