Question could some one look at this this the second time I summiting A particle with charge –5.74 × 10-6 coulombs is released at rest in a region of constant, uniform electric field. Assume that gravitational effects are negligible. At a time 2.86 seconds after it is released, the particle has a kinetic energy of 4.96 × 10-9 joules. How long after the particle is released has it travelled through a potential difference of 0.351 volts?
Explanation / Answer
potential difference is proportional to distance travelled (s)
similarly s is proportional to (1/2 XaccX t2)
but acc=force/mass
force=Eq
E=electric field magnitude so
s=(Eq/mass)t2E can be calculated from the given value of kinetic energy
as E=ke /chargeX distance
following this line we will get the answer.
