4) Two charges q1 and q2 are placed Δx apart. A third particle of mass 20 µg and charge q3 is placed between the two particles such that it is 25 cm from particle q1 as shown in the diagram below. Determine the magnitude and direction of the acceleration of q3 due to the net force on it by the two other charges.

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.
