．2008年9月25日中国“神舟七号”宇宙飞船顺利升空，9月27日，中国宇航员首次实现太空出舱．下一步我国将于2015年发射空间站，设该空间站体积很大，宇航员可以在里面进行多项体育活动，一宇航员在站内玩垒球(万有引力可以忽略不计)，上半侧为匀强电场，下半侧为匀强磁场，中间为分界面，电场与分界面垂直，磁场垂直纸面向里，电场强度为E＝100V/m，宇航员位于电场一侧距分界面为h＝3m的P点，PO垂直于分界面，D位于O点右侧，垒球质量为m＝0.1kg，带电量为q＝－0.05C，该宇航员从P点以初速度v0＝10m/s平行于界面投出垒球，要使垒球第一次通过界面就击中D点，且能回到P点．求：

(1)OD之间的距离d.

(2)垒球从抛出第一次回到P点的时间t.(计算结果保留三位有效数字)
