| What causes a positively charged particle to gain speed when it is accelerated through a potential difference? |
The particle accelerates because it loses potential energy as it moves from high to low potential. The particle accelerates because it loses potential energy as it moves from low to high potential The particle accelerates because it gains potential energy. The particle accelerates because it moves towards negative charges. |
| The particle accelerates because it loses potential energy as it moves from high to low potential. |
| Because the potential energy of the positive charge decreases, it is moving in the same direction as the electric force, and the electric force does positive work on the positive charge to increase its kinetic energy which increases the velocity. Also to comply with law of energy conservation. |
