Vedclass · Answer

(B) The force on a moving charge in a magnetic field is given by the Lorentz force formula: $\vec{F} = q(\vec{v} 	imes \vec{B})$.Here,the charge of the electron is negative $(q = -e)$.The velocity $\vec{v}$ is towards the east,and the magnetic field $\vec{B}$ is towards the north.Using the right-hand rule for the cross product $\vec{v} 	imes \vec{B}$,the direction of $\vec{v} 	imes \vec{B}$ is vertically upward (from east to north).Since the electron has a negative charge,the force $\vec{F} = -e(\vec{v} 	imes \vec{B})$ will be in the opposite direction of $\vec{v} 	imes \vec{B}$.Therefore,the force on the electron is directed vertically downward.

An electron moving towards the east enters a magnetic field directed towards the north. The force on the electron will be directed
