The charge of an electron is 1.60 × 10−19 C. A proton is moving along the positive x-axis with a speed of 1.50 × 105 m/s in a magnetic field of 2.00 T that is oriented along the positive y-axis.
b. Find the direction and magnitude of the electromagnetic force on the proton.

c. What is the force when the proton moves along the y-axis?

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.

Answerthe valence of an element or radical is equal to the number of positive or negative charges on the ion.

F  you double the  force, you double the acceleration, but  if  you double the  mass, you velocity. all bodies accelerate at the  same  rate regardless of size or  mass.
