Explanation:
When a charge is moved against the Coulomb force of an electric field, it requires an external force to overcome the force of the electric field. This external force does positive work on the charge to move it against the electric field. Therefore, option 'B' is the correct answer.
Further explanation:
- Coulomb force: The force of attraction or repulsion between two charges is known as Coulomb force. This force acts along the line joining the charges and is proportional to the product of charges and inversely proportional to the square of the distance between them.
- Electric field: An electric field is a region in space where a charged particle experiences a force due to the presence of other charges. The strength of the electric field at any point is defined as the force experienced by a unit charge placed at that point.
- Work: Work is defined as the product of force and displacement in the direction of the force. When a force is applied on an object, it can either do positive work (when the force and displacement are in the same direction) or negative work (when the force and displacement are in opposite directions).
- Energy: Energy is the ability to do work. The energy of a system is the sum of its kinetic energy (energy due to motion) and potential energy (energy due to position or configuration).
Conclusion:
When a charge is moved against the Coulomb force of an electric field, an external force is required, which does positive work on the charge to move it against the electric field. This work is done by utilizing some energy from an external source. Therefore, option 'B' is the correct answer.
