Question
A particle of charge -0.8\,\mathrm{\mu C}−0.8μC is located at the end of a spring at some equilibrium position (left diagram). When another particle with charge +0.6\,\mathrm{\mu C}+0.6μC is placed 8.5\,\mathrm{cm}8.5cm below it, it drops by 3.5\,\mathrm{cm}3.5cm (after any transient motion has died out). The resulting distance between the two charged particles is 5\,\mathrm{cm}5cm.
What is the spring constant, k_{s}ks, of the spring in \mathrm{N/m} N/m?
