A particle with charge -3.74 × 10-6 coulombs is released at rest in a region of constant, uniform electric field. Assume that gravitational effects are negligible. At a time 9.36 seconds after it is released, the particle has a kinetic energy of 2.25 × 10-8 joules. How long after the particle is released has it traveled through a potential difference of 0.351 volts?
