Final answer:
Neither the components of momentum (p) nor the components of angular momentum (L) are conserved in motion in the given fields. Additional information is needed to determine whether momentum or angular momentum is conserved.
The correct answer is d) Neither p nor L.
Step-by-step explanation:
In motion in the given fields, neither the components of momentum (p) nor the components of angular momentum (L) are conserved.
In order to determine whether momentum or angular momentum is conserved in a specific situation, additional information is needed.
The conservation of momentum (p) and angular momentum (L) depends on the presence of external forces and torques acting on a system. Linear momentum is conserved when no external forces act on a system. Conversely, angular momentum is conserved when no external torques influence a system.
In the context of the given information, and without external influences, we can apply the principle that momentum alone is conserved in collisions where kinetic energy may not be conserved. However, angular momentum is conserved under the condition that there is no net external torque acting on the system.
Considering the scenarios such as Compton scattering, conservation of energy and momentum are observed, further implying that in collision problems, as long as no external forces or torques are acting, both linear momentum and angular momentum can be conserved.
