Explanation:
SCIENCE
Two point charges are 10.0 cm apart and have charges of 2.0 μC and –2.0 μC, respectively. What is the magnitude of the electric field at the midpoint between the two charges? 8.99*10^9(2*10^-6/.025)=719200 Two equal charges are separated by 3.7 x 10-10
Physics
How would the electrostatic force change if Coulomb's law included a negative sign? It would depend on the magnitude of the charges. Like charges would attract, and opposite charges would repel.*** It would not make a difference in the electrostatic force.
