In a neighborhood park, a child of mass m sits in a swing and is swinging back and forth. The seat of the swing is supported by two chains, each of length R. When the child is at the lowest point in the swinging motion, the tension in each chain is T. (Use any variable or symbol stated above along with the following as necessary: g.) (a)

Assume that two of the electrons at the negative terminal have attached themselves to a nearby neutral atom. there is now a negative ion with a charge -2e at this terminal. what are the electric potential and electric potential energy of the negative ion relative to the electron? the electric potential and the electric potential energy are both twice as much. the electric potential is twice as much and the electric potential energy is the same. the electric potential is the same and the electric potential energy is twice as much. the electric potential and the electric potential energy are both the same. the electric potential is the same and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron. the electric potential is twice as much and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron.
