The capture or scattering of an initially straight infinite test cosmicstring by a Kerr-Newman black hole, or by any other small source of anelectrovac gravitational field, is analyzed analytically when the string moveswith initial velocity v and large impact parameter b >> M so that the stringstays very nearly straight (except during the final capture process, if thatoccurs, or except far behind the gravitating object, if b is not much greaterthan the energy of the object in the frame of the string). The critical impactparameter for capture at low velocities is shown to be[(pi/2)(M^2-Q^2)/v]^{1/2}. For all larger b, the displacement of the stringfrom the plane of the gravitating object after the scattering approaches thefinal value [b^2 - (pi/2)(M^2-Q^2)/v]^{1/2} - 2 pi M v/(1-v^2)^{1/2}, for anyv, so long as b >> M.Comment: 27 pages, no figures, Late
