A particle with charge -3.74 x 10-6 coulombs is released at rest in a region of constant, uniform electric field. Suppose that gravitational effects are negligible. At a time 5.86 s after it is released, the particle has a kinetic energy of 4 x 10-9 joules. Compute how long after the particle is released has it travelled through a potential difference of 0.351 volts?
