A negatively charged particle is moving to the right, directly above a wire having a current flowing to the right, as shown below. In which direction is the magnetic force exerted on the particle?Answera. out of the pageb. into the pagec. upwardd. downwarde. The magnetic force is zero since the velocity is parallel to the current.

Explanation:

As the current in the ire is towards right and the charge particle is above the wire, the direction of magnetic field due to the current carrying wire is perpendicularly outwards to the plane of paper. It is calculated by the Maxwell's right hand thumb rule. Now by using the Fleming's left hand rule, the direction of force is upwards.
