Problem

An oil droplet of mass

2.0\times10^{-6}\,\text{kg}

carries a charge of

-1.2\times10^{-8}\,\text{C}

. The droplet is to be held stationary midway between two large horizontal plates separated by

0.80\,\text{cm}

. Assuming the upper plate is positive, what potential difference between the plates is required? a)

1.3\times10^{2}\,\text{V}

1.3\,\text{V}

13\,\text{V}

1.6\times10^{3}\,\text{V}
