Coulomb’s Law
A massless sphere of charge q1 = 0.640 µC is at the end of a
spring in equilibrium as shown below in figure a. When a charge q2
= -0.410 µC is held beneath the positively charged sphere as shown
in figure b, the spring stretches by a distance d = 3.60 cm from
its position in figure a. When equilibrium is reestablished, the
distance r between the charges is 5.20 cm. What is the spring
constant of...
