问题提出如图1所示,在光滑水平面上,有垂直桌面向下的匀强磁场B,现有一绝缘的、内壁光滑的玻璃管放在水平面上,管的质量为M,管中有一小球,球的质量为m,带电量为+q,管的直径略大于球的直径.现在给管一个水平初速度v0,试管和球将怎样运动?(已知管足够长,磁场范围足够大)
The problem is presented in Figure 1, on a smooth horizontal surface, there is a vertical magnetic field B down the desktop, the existing an insulating, smooth glass tube on the horizontal surface, the tube of quality M, the tube has a small ball , The mass of the ball is m, the charge is + q, and the diameter of the tube is slightly larger than the diameter of the ball. Now give the tube a horizontal initial velocity of v0 and how will the tube and the ball move? (Given that the tube is long enough and the magnetic field is large enough)
