A taut ideal, massless rope should havetension (i.e., constant magnitude oftension force) between two endpoints provided no external forces parallel to the rope act on itBETWEENthe endpoints: there will in general be external applied forces to hold it taut atthe endpoints. The rope does not have to be straight. It can be wrapped around constraints aslong as their surfaces exert no parallel forces on it.a) wildly varyingb) constantc) complexly varyingd) zeroe) 9.8 N/kg.
