Answer:
Explanation:
According to Coulomb's law, the magnitude of the electric force between two equals charges (q) is given by:
Here k is the coulomb constant and d is the distance between the charges. For two electrons we have:
Answer:
599 N/m
Explanation:
Let k (N/m) be the spring constant. According to the law of energy conservation, the total mechanical energy (kinetic and elastic) any any point along the spring must be the same:
Answer:
2.82 D
Explanation:
