Problem

A positively charged particle travels through perpendicular uniform electric and magnetic fields, moving such that its velocity is perpendicular to both fields. Which of the following relationships between the particle’s speed

v

and the field magnitudes

E

and

B

must be satisfied for the particle to experience zero net force? a)

v = \dfrac{2E}{B}

v = \dfrac{E}{B}
