Potential energy

  1. Apr 14, 2008 #1
    A proton is brought near a positively charged sphere. As it is brought closer its potential energy...

    A. increases
    B. decreases
    C. remains the same
    D. cannot determine

    Does it decrease (B) because same forces repel causing a decrease in PE?

    I would say that it increases because you need to do some work in order to bring the proton near the positively charged sphere.
