Which description best matches the image below of a hand that is using the right-hand palm rule?

a. a proton moving toward you in a magnetic field that points up will experience a force to the right.

b. a proton moving up in a magnetic field that points to the right will experience a force toward you.

c. a proton moving to the right in a magnetic field that points up will experience a force toward you.

d. a proton moving to the right in a magnetic field that points toward you will experience a force up.

The correct option is C. i.e.A proton moving to the right in a magnetic field that points up will experience a force toward you.

Explanation:

As seen in the diagram, the magnetic field points in the upward direction. The charge moves towards the right. Then, as per the right hand thumb rule, the force will be towards you. 

Because we know, F = qvB
where q is charge
v is the velocity of the charge.
B is the magnetic field.

Force is perpendicular to the plane of v & B.

 

stands for electromotive force and it is measured in volts. despite its name, it is not actually the force in the sense of being a "pushing" or "pulling" (not measured in newtons).an equation that relates emf,  ℰ,  to a battery's terminal voltage, v, current, i, and internal resistance, r, is    ℰ = v + irin this case, the emf can be interpreted as a voltage—a difference in electric potential.i would not say that it would be considered an energy. if emf can be defined as the energy/work per a unit charge from a battery or other electric source, then it is not strictly energy.
