A2L: Assessing-to-Learn Physics

The potential at two points in space is: V₁=200 Volts, V₂=300 Volts. Which of the following statements is true for moving a point charge, q, from point 1 to 2?

1. The work done by an external agent to move q from point 1 to 2 is positive.
2. Can’t determine the work done because you don’t know the direction of V at the two points.
3. The work done by the electrical force exerted on q in moving it from point 1 to 2 is: W = -q(100 Volts).

1. A
2. B
3. C
4. A and B
5. A and C
6. A, B, and C
7. None of the above
