電気双極子がつくる電場の導出過程において、 赤線部分の式変形が分かりません。 ご解説よろしくお願い致します。

9 電荷と静電場 電荷の大きさを4, 負の電荷から正の電荷にいたるベクトルをdとするとき, p=gd をその電気双極子の双極子モーメントという (図 9.26) 電気双極子がどのような電場をつ (9.43) くるかはpによっている。 一酸化炭素COや水H2Oなどの分子は電気的に中性だが,電子による負の電荷の分布の中 心と原子核による正の電荷の中心が少しずれている。このような分子は電気的には電気双 極子とみなすことができる. 電気双極子による電場を,まず電位を求め,それから式 (9.42)によって電場を計算す る,という方法で求めてみよう. 1 V(r)= 4760 (√r-d/2\_\r+d/21) 正負の電荷の中心を原点とし,正の電荷g はd/2に,負の電荷-gはd/2にあるとする. このとき, rにおける無限遠を基準点にする電位は,式 (9.37 ) により 191 図 9.26 電気双極子 1 \r-d/2 = (r²-d.r) + = 1/(1+d+r) となる。第2項はdの符号を変えればよいから, となる.ここで|d|は小さく, |d|<|r|であるとして, dについて1次までの近似でV(r) を 計算する. 式 (9.44) の( )内の第1項では, dについて2次以上の項を無視すれば, |r-d/2|=(r-d/2)・(r-d/2) r²-d.r したがって,式 (A.28) の近似を使って dr \r+d/2₁ ==—= (1-2;r) となる。これを式 (9.44) に代入し, (9.44)
