A positively charged oil droplet remains in the electric field between two horizontal plates, separated by a distance 1 cm. If the charge on the drop is 3.2x10^(-19) C and the mass of the droplet is 10^(-14) kg what is the potential difference between the plates? Now if the polarity of the plates is reversed what is the instantaneous acceleration of the droplet?

Solution:
A positively charged oil droplet remains in the electric field between two horiz
