Answer

The work done on the particle by the force is zero.

Work Step by Step

The work is equal to the change in kinetic energy of the particle. Since the particle's final speed is equal to the particle's initial speed, the change in kinetic energy is zero. Therefore, the work done on the particle by the force is zero.
