Potential difference and power — practice question

A uniform electric field is shown by five horizontal field lines. P and Q are two points within the field. Because of the field, a positively charged particle in a vacuum travels from P to Q. Which statement has to be true?

  • AThe acceleration of the particle between P and Q is increasing.
  • BThe kinetic energy of the particle at P is the same as the kinetic energy of the particle at Q.
  • CThe force on the particle at Q is greater than the force on the particle at P.
  • DWork is done on the particle as it moves from P to Q.
