A uniformly charged, thin ring has radius 15.5 cm and total charge +23.3 nC. An electron is placed on the ring’s axis a distance 26.1 cm from the center of the ring and is constrained to stay on the axis of the ring. The electron is then released from rest. Find the speed of the electron when it reaches the center of the ring. (Give your answer in scientific notation using m/s as unit)
An electric dipole consists of a negative charge- located at (0,-) and a positive charge +q located at (0, +3).
