Vedclass · Answer

(D) The magnetic force $F$ acting on a charged particle moving in a magnetic field is given by the Lorentz force formula: $F = q(\vec{v} 	imes \vec{B}) = qvB \sin(	heta)$.Here,$	heta$ is the angle between the velocity vector $\vec{v}$ and the magnetic field vector $\vec{B}$.Since the electron enters the magnetic field in the same direction as the magnetic field,the angle $	heta = 0^\circ$.Therefore,the magnetic force $F = qvB \sin(0^\circ) = 0$.Since the net force on the electron is zero,there is no change in its velocity (both magnitude and direction remain constant). Thus,the velocity of the electron remains unchanged.

If an electron enters a magnetic field with its velocity pointing in the same direction as the magnetic field,then
