Problem

A parallel-plate capacitor has a plate separation of

1.5\,\text{cm}

and is maintained at a potential difference of

300\,\text{V}

. A

4.0\,\text{g}

particle carrying a charge of

2.0\,\mu\text{C}

is released from rest at the negative plate. Neglect gravity. Approximately how long does the particle take to reach the positive plate? (a)

0.039\,\text{s}

(b)

0.11\,\text{s}

(c)

0.055\,\text{s}

(d)

0.17\,\text{s}
