Part A

Raindrops acquire an electric charge as they fall.

Suppose a $2\mathrm{.}0-$mm$-$diameter drop has a charge

of $+13pC.$ In a thunderstorm, the electric field

under a cloud can reach $15,000\frac{N}{C},$ directed

upward.

For a droplet exposed to this field, how do the magnitude of the electric

force compare to those of the weight force?
