Q9:

Two positively charged particles exert a repulsive force on each other that increases as they are brought nearer to each other. What is the name given to this force?

  • AElectrostatic repulsion
  • BGravitational attraction
  • CElectromagnetic repulsion
  • DElectrostatic attraction
  • EMagnetic repulsion

Q10:

The graph shows the force experienced by two charged particles against how far apart they are. If positive values on this graph represent a repulsive force, what are the charges of the two particles?

  • AEither two positive or two negative charges
  • BTwo positive charges
