Question

A particle having a charge of q = +70 C and unknown massm is released from rest xi =1.0 meters abovethe center of a ring having a radius of a = 0.6m. The ringhas a charge Q = +123 C that is uniformly distributedaround the ring, and the ring is held fixed in place. It isobserved that particle rises to where it is xf = 2.0meters above the center of the ring before it starts to falltowards the center of the ring. Determine the mass of theparticle.
a. 1.0 kg b. 2.0 kg c. 3.0 kg d. 4.0 kg e. 5.0 kg
a. 1.0 kg b. 2.0 kg c. 3.0 kg d. 4.0 kg e. 5.0 kg
