Two equal but opposite-sign point charges of 3 C are held x meters apart by a spring
Question:
Two equal but opposite-sign point charges of 3 μC are held x meters apart by a spring that provides a repulsive force given by Fsp = 12(0.5 − x) N. Without any force of attraction, the spring would be fully extended to 0.5 m.
(a) Determine the charge separation.
(b) What is the dipole moment?
