Two identical objects (A, B) travel circles of the same radius, but object A completes three times as many rotations as object B in the same time.
The net centripetal force acting on object B is:

a) one-ninth the force acting on object A.
b) one-third the force acting on object A.
c) three times the force acting on object A.
d) nine times the force acting on object A.
e) the same as the force acting on object A.
Explain your choice.

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.
