The electric potential at a location 1 m from a certain charged particle is 4 times the potential at a location 1 m from a different particle. How do the particles' charges compare? (These are two separate trials; assume that only one particle is present for each trial.) Group of answer choices The first particle has 1/4 the charge of the second particle. The first particle has 1/16 the charge of the second particle. The first particle has 16 times the charge of the second particle. The first particle has 4 times the charge of the second particle
