Question
A small sphere of charge q1 = 0.872 C hangs from the end of a spring as in Figure a. When another small sphere of charge q2 = -0.624 C is held beneath the first sphere as in Figure b, the spring stretches by d = 3.75 cm from its original length and reaches a new equilibrium position with a separation between the charges of r = 4.70 cm. What is the force constant of the spring?
N/m
Explanation / Answer
kd = k q1 q2/r^2
k = (9E9*0.872e-6*0.624E-6/4.7E-2^2)/3.75E-2=59.12
