Two charged particles with opposite signs but the same magnitude of charge enter a magnetic field that is
perpendicular to their direction of motion. How will the motion of the two particles differ when they enter the magnetic field?

Explanation:

If θ=90°, the force acting on the particle is the maximum possible and the direction of the force is perpendicular to the path of the particle. The particle then moves along a circular path with the force acting as the centripetal force.

The magnetic field does no work, so the kinetic energy and speed of a charged particle in a magnetic field remain constant. The magnetic force, acting perpendicular to the velocity of the particle, will cause circular motion.

i think the answer is a, hope this : )

higher potential

explanation:

because it is in a high speed so it must move into a of high potential
