如图所示，水平放置的平行板电容器，原来AB两板不带电，B极板接地，它的极板长L= 0．1m，两板间距离d = 0．4 cm，现有一微粒质量m=2．0×10^-6kg，带电量q=+1．0×10^-8C，以一定初速度从两板中央平行于极板射入，由于重力作用微粒恰好能落到A板上中点O处，取g=10m/s²．试求：

（1）带电粒子入射初速度的大小；

（2）现使电容器带上电荷，使带电微粒能从平行板电容器的右侧射出，则带电后A板的电势为多少？

Earl has been employed by Flash Co, for the past 20 years. During that time he has also invested in the company in the form of shares and debentures. Earl owns 5,000 ordinary shares in Flash Co. The shares are of $1 nominal value and are paid up to the extent of 75%. The debentures, to the value of $5,000, are secured by a fixed charge against the land on which Flash Co’s factory is built.
