If there were no voltage on the plates, we would expect everything to be over here in some negative value falling.
如果板子上没有速度,这些可能都在这,都是负值下降的。
When the charge is applied, if the upper plate is negative, we would expect that the negative droplet would be repelled at a rate exceeding the gravitational fall.
当电荷起作用时,如果上边的板子是负电的,我们可以期待负电的液滴会,超过重力下降速度的速度被排斥。
A much smaller peak, a much less rapid decline after the peak occurs.
