• Integration helps in summing up the contributions of all charges in the system to determine the total potential energy.

• Integration simplifies the calculation of kinetic energy instead of potential energy.

• Integration is not relevant in determining the potential energy of a system of charges.

• Integration only considers the potential energy of one charge in the system.

How can integration be utilized to find the work done in moving a charge in an electric field?

• By multiplying the charge by the electric field strength
