**Interaction of String with the Particle in Curved Spacetime**

**Abstract:**

Within the framework of generalized Papapetrou method, we derive the
effective equations of motion for a string with two particles attached at
the ends, along with appropriate boundary conditions. The equations of
motion are the usual Nambu-Goto-like equations, while boundary conditions
turn out to be equations of motion for the particles at the string ends.
The form of those equations is discussed, with the emphasis on the force
that the string exerts on the particle. It turns out that this force has
some formal similarity with the Lorentz force law of electrodynamics.
