1. Coulomb's Law describes a force that can both attract and repel. In the cases below, which way would the electric force act? Circle ATTRACT, REPEL, or NEITHER to indicate your
a.
42 = -1.10€
42 = 7.6x102C
b
4 = 4.2x10°C
9. = 3mc
9, = -8x10-37C
4 = 4n
ATTRACT | REPEL I NEITHER
ATTRACT / REPEL / NEITHER
ATTRACT 1 REPEL / NEITHER
ATTRACT / REPEL I NEITHER
ATTRACT | REPEL I NEITHER
C.
92 = 7.2C
d.
92 = -40%
92
= 6.7x10-15C
e.
9 = OC

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.
