两等量点电荷的连线的中垂线上的场强与电势分别如何变化?两等量点电荷可分为四种情况,两等量的正点电荷、两等量的负点电荷、两等量的异号电荷(一正一负或一负一正),而两等量的正点电荷与两等量的负点电荷情况相似,两等量异号电荷的情况相似,所以分两等量正点电荷和两等量异号电荷(一正一负)两种情况来讨论. 1.两等量正点电荷连线的中垂线上的场强与电势 How are the field strengths and electric potentials of the two-point electric charges on the perpendicular lines changed? The two equal-value electric charges can be divided into four cases: two equal positive charges, two equal negative charges, and two Equal amounts of different charges (one positive or one negative or one negative and one positive), and two equal amounts of positive point charges are similar to two equal amounts of negative point charges, and two equal amounts of different charges are similar, so they are divided into two classes. The amount of positive charge and two equal quantities of different charges (one positive and one negative) are discussed in two cases. 1. The field strength and potential on the perpendicular line of two equal-point charge connections
