Final answer:
The force on an electron depends on the distance from the point charge, the charge of the point charge, and the velocity of the electron in the context of a magnetic field. Mass does not affect force but does affect acceleration. Direction of force is influenced by both the charge and the magnetic field.
Step-by-step explanation:
The force on an electron depends on several factors. These include: 1) the distance from the point charge, since the force is inversely proportional to the square of the distance according to Coulomb's Law; 2) the charge of the point charge, as the force is directly proportional to the product of the charges involved; and 4) the velocity of the electron, particularly when considering a magnetic field since the magnetic force is a result of moving charges. The mass of the electron (3) Mass of the electron) will not affect the electric or magnetic force on it, although it will affect the electron's acceleration as a result of a force. The 5) direction of the force is determined by the nature of the charges (attractive force for opposite charges, repulsive for like charges) and the direction of the magnetic field in relation to the velocity of the electron.
Increasing the magnitude of a uniform magnetic field through which a charge is traveling will increase the magnetic force on the charge, as the magnetic force is proportional to the magnetic field strength. Changing the direction of the field will change the direction of the force on the charge, but not necessarily its magnitude.
