barron 和 princeton辅导书 上的右手定则怎么和我知道的不一样啊我已经快被搞疯掉了barron上说if the fingers of flat right hand point in the direction of the field,and the thumb is in the direction of electron flow,the hand will push in the direction of magnetic forceprinceton的搞得我头还要晕：point your thumb in the direction of V and your fingers in the direction of B.If q is postive,F points out of the palm.If q is negative,F points into the palm.我就是不懂,我高中讲的右手定则就是B V 和电流 怎么barron里又多了一个磁场力 princ

barron 和 princeton辅导书 上的右手定则怎么和我知道的不一样啊
我已经快被搞疯掉了
barron上说if the fingers of flat right hand point in the direction of the field,and the thumb is in the direction of electron flow,the hand will push in the direction of magnetic force
princeton的搞得我头还要晕：point your thumb in the direction of V and your fingers in the direction of B.If q is postive,F points out of the palm.If q is negative,F points into the palm.
我就是不懂,我高中讲的右手定则就是B V 和电流 怎么barron里又多了一个磁场力 princeton还要考虑正电荷还是负电荷
答
啊哦,这个.你还是按照你高中讲过的做题吧.物理就是物理,永远不会有错的,除非原来理论被推翻,仔细看了一下我也搞不清了,忽略我原来的回答.毕竟巴朗不是教科书,而是练习册罢了.
