Suppose you have a positive charge and a negative charge which are each fixed in place. If you were to place a small positive charge right in the middle between them and let go, which way would that charge start to move? Toward the negative charge, because the positive charge repels it and the negative charge attracts it.   Neither direction, because no net force acts on the charge when it's in the middle.   The direction it starts moving in is random.   Toward the positive charge, because the positive charge attracts it and the negative charge repels it

Electric Charges and Fields

One of the fundamental properties is the electromagnetic property. Charge cannot be destroyed by any process and this contributes formally to the law of charge conservation.
