A small sphere of charge q1 = 0.816 µC hangs from the end of a spring as in figure a. When another small sphere of charge q2 = −0.636 µC is held beneath the first sphere as in figure b, the spring stretches by d = 3.72 cm from its original length and reaches a new equilibrium position with a separation between the charges of r = 5.15 cm. What is the force constant of the spring?

Question
A small sphere of charge q1 = 0.816 µC hangs from the end of a spring as in figure a. When another small sphere of charge
q2 = −0.636 µC
is held beneath the first sphere as in figure b, the spring stretches by d = 3.72 cm from its original length and reaches a new equilibrium position with a separation between the charges of r = 5.15 cm. What is the force constant of the spring?
