Princeton Review 16th Edition PT1 Q59


59) This question asks us to consider the electric potential energy of the given situations and select which answer choice describes the greatest electric potential energy. This is the equation for the electric potential energy between two charges.

Where U is electric potential energy, k is Coulomb's constant, Q is magnitude of charge, and r is distance between the charges

Since all the answer choices include the same charges for Q1 and Q2 and k is a constant, the only variable element in this equation would be r, the distance between the charges. This means the answer choice where the charges are closest will correlate to the highest electric potential energy. Choice E has the smallest magnitude of r.


Answer: E
