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...

Two metal spheres, each of mass 0.30 g, are suspended by massless strings from a common pivot point at the ceiling, as shown in the figure. When both spheres carry the same electric charge, we find that they come to an equilibrium when each string is at an angle of θ·4.5. with the vertical. If each string is 20 cm long, what is the amount of the charge on each sphere? (Enter the magnitude in nc.) nC
