阅读下边一首诗，完成后面问题。
                                                                                                                                    幽居初夏 陆游
                                                                                                                  湖山胜处放翁家，槐柳阴中野径斜。
                                                                                                                  水满有时观下鹭，草深无处不鸣蛙。
                                                                                                                  箨龙已过头番笋，木笔犹开第一花。
                                                                                                                  叹息老来交旧尽，睡来谁共午瓯茶。
       注箨（zé）龙，就是笋。木笔，又名辛夷花。两者都是初夏常见之物。瓯(ōu)：杯子。

如图甲所示，绝缘轻质细绳一端固定在方向相互垂直的匀强电场和匀强磁场中的O点，另一端连接带正电的小球，小球电荷量q=6×10^﹣7C，在图示坐标中，电场方向沿竖直方向，坐标原点O的电势为零．当小球以2m/s的速率绕O点在竖直平面内做匀速圆周运动时，细绳上的拉力刚好为零．在小球从最低点运动到最高点的过程中，轨迹上每点的电势φ随纵坐标y的变化关系如图乙所示，重力加速度g=10m/s²．则下列判断正确的是（  ）
