    偶极矩为[tex=0.571x1.0]FGGpnaR8m8C48rN8O0c7aw==[/tex]的电偶极子处在外电场[tex=0.786x1.0]I/kNMtd8YcgkWCrgriW/hA==[/tex]中:(1)若[tex=0.786x1.0]I/kNMtd8YcgkWCrgriW/hA==[/tex]是均匀的,当[tex=0.571x1.0]FGGpnaR8m8C48rN8O0c7aw==[/tex]与[tex=0.786x1.0]I/kNMtd8YcgkWCrgriW/hA==[/tex]的夹角[tex=0.5x1.0]qm+hGi0qngLh1B7HsENMPg==[/tex]为何值时电偶极子达到平衡?此平衡是稳定平衡还是不稳定平衡?(2)若[tex=0.786x1.0]I/kNMtd8YcgkWCrgriW/hA==[/tex]是不均匀的,电偶极子能否达到平衡?
